This works well for a small number of vertically stacked charts, however if you have lots of charts you’ll probably want to scroll rather than fit them all onto the page. The following section provides tips on how to get the best possible fit for a given graphic. To specify that a page should be accessed via a navigation bar menu you use the data-navmenu attribute. If you have a large dataset where you want to enable pagination, you should be sure to specify the pageLength option to show more than the default 10 rows of your dataset per page: To include a DataTable within a Shiny flexdashboard you need to be sure to wrap the datatable output in DT::renderDataTable (so that it is updated when inputs it depends on change). Plotly, which via it’s ggplotly interface allows you to easily translate your ggplot2 graphics to an interactive web-based version. You can layout one or more pages of a dashboard as storyboards and then use traditional row and column layout on the other pages. There are also several ways to add interactivity to flexdashboards. To do this, you exclude the storyboard: true option and instead add the {.storyboard} class to pages you want laid out as storyboards. This is done by adding the data-orientation attribute to the header of the page you want to change the orientation of. Return all the available packages using. Value boxes for highlighting important summary data. For custom colors you can also specify any valid CSS color (e.g. For example, the following dashboard includes some content at the top and a dashboard section that contains only text: Each component within a dashboard includes optional title and notes sections. Each component will be allocated it’s own frame in the storyboard, with the section title used as the navigation caption. Load the libraries flexdashboard, shiny, dplyr, and plotly. The bslib R package provides tools for creating custom Bootstrap themes directly from R, making it much easier to customize the appearance of Shiny apps & R Markdown documents. Note that if you want to use DataTables with flexdashboard you should install the very latest version of the DT (v0.2) from CRAN (it contains some changes required for flexdashboard compatibility): To include a DataTable you use the DT::datatable function: Note that we specified the bPaginate = FALSE option. For example: Dashboard layout is done using the browser flexbox engine, which alters its items’ width and/or height to best fill the available space on any display device. The flexdashboard layout system also adapts itself intelligently for display on mobile devices. 40-50 or less). If you want to customize these colors you should create a CSS stylesheet with the requisite navbar-inverse entries and include it using the css option of the flex_dashboard format. Each level 2 header ( ## ) begins a new column. ap <- available.packages() See also Names of R's available packages, ?available.packages.. For example, this layout defines two rows, the first of which has a single chart and the second of which has two charts: By default flexdashboard charts are laid out to automatically fill the height of the browser. R graphical output including base, lattice, and grid graphics. 3. To layout a row or column as a tabset you simply add the {.tabset} attribute to the section heading. For example, if you have a page with the anchor “#details” you could link a gauge to it as follows: To include a gauge within a Shiny flexdashboard you need to be sure to wrap the gauge output in renderGauge (so that it is updated when inputs it depends on change). You can specify a set of custom color sectors using the gaugeSectors function. For some chart types this might not be ideal. See Icon Sets above for details on the icons available for use within the navigation bar. For example, the following code lays out the second column in tabset: Rows can also be laid out as a tabset as illustrated here: Note that here we also apply the {.tabset-fade} attribute which results in a fade in/out effect when switching tabs. At the moment, bslib provides support for Bootstrap 4 and 3 as well as their various Bootswatch themes. For larger dataset sizes the use of standard R graphics (described below) may be preferable. A flexbox layout expands items to fill available free space, or shrinks them to prevent overflow. Available colors include “primary”, “info”, “success”, “warning”, and “danger” (the default is “primary”). “fa-github”, “ion-social-twitter”, “glyphicon-time”, etc.). a scatter trace with mode="markers") enjoys a lot of the same properties as add_markers() (i.e. Here’s an example of a row based layout that includes 3 charts from R base graphics: We’ve specified an explicit fig.height and fig.width for each chart so that their rendered size fits their flex container as closely as possible. R users are doing some of the most innovative and important work in science, education, and industry. Optionally use Shiny to drive visualizations dynamically. For example, this dashboard displays 3 charts split across two columns: In this example we’ve moved Chart 1 into its own column which it will fill entirely. For example, the following adds an “About” link to the left side of the navigation bar: Navigation bar items must include either a title or icon field (or both). For example, if you have a page with the anchor “#details” you could link a value box to it as follows: You can specify icons from three different icon sets: When referring to an icon you should use it’s full name including the icon set prefix (e.g. For static dashboards, you should use the knitr::kable function to output your dataset, for example: For Shiny based dashboards you should use the shiny::renderTable function, for example: This ensures that the tabular display is updated when the inputs upon which it depends change. Moreover, the add_text() function (i.e. Both styles of page linking are demonstrated in this example: The typical means of navigating between pages is the global navigation bar as described above. Tabular data (with optional sorting, filtering, and paging). Gauges for displaying values on a meter within a specified range. For example: You can add an icon to the navigation menu for a page using the data-icon attribute. You can also add social links and a link to view the source code of the dashboard. For a more complete example, see the HTML Widgets Showcase storyboard. Support for a wide variety of components including htmlwidgets; base, lattice, and grid graphics; tabular data; gauges and value boxes; and text annotations. tablets) is the same as for larger desktop screens (any screen with width greater than 768 pixels is considered a medium screen). The align field is optional (it can be “left” or “right” and defaults to “right”). R developers continue to extend the reach of R. November featured a new package on Archaeology, one of only seventeen I could find on CRAN pkgsearch::pkg_search(query="Archaeology ",size=200), as well as a package that wraps Python’s chess package. Rows and columns are allocated using the default figure sizes and respect the relative proportions established via the use of data-widthattributes. If your layout has multiple columns then the columns will split the available width evenly (unless overridden via the data-width attribute as described below). For example, the following dashboard includes a storyboard on the first page (“Analysis”) as well as another page (“Details”) that uses conventional layout: You may wish to add commentary alongside the frames in your storyboard. You can do this from within RStudio using the New R Markdown dialog: Note that the ideal values for these dimensions typically need to be determined by experimentation. DataTables always use pagination (again, so that scrolling the DataTable doesn’t interfere with scrolling the overall display). Install the flexdashboard package from CRAN as follows: To author a flexdashboard you create an R Markdown document with the flexdashboard::flex_dashboard output format. https://github.com/rstudio/flexdashboard/tree/feature/logo-and-favicon/inst/rmarkdown/templates/flex_dashboard/resources. The sectors option enables you to specify a set of three value ranges (“success”, “warning”, and “danger”) which cause the gauge’s color to change based on it’s value. For example, this layout defines a single column with two charts that fills available browser space: Depending on the nature of your dashboard (number of components, ideal height of components, etc.) The Layouts page includes a variety of sample layouts which you can use as a starting point for your own dashboards. If your layout has a single column then charts will occupy the full width of the browser. The layout of dashboard components for medium sized mobile screens (e.g. dygraphs, which provides rich facilities for charting time-series data and includes support for many interactive features including series/point highlighting, zooming, and panning. For example, this dashboard hides it’s second component on mobile devices: It’s also possible to create a mobile-specific version of a given dashboard component that will be used in place of the default version. By default the current theme’s “success” color (typically green) is used for the gauge color. Get offline access to CRAN, PyPI, and Bioconductor, share local packages, restrict package access, find packages across repositories, and more. Source code can either be embedded into the document (source_code: embed) or can be a link to a URL where the source code can be found online (e.g. You can use the valueBox function to display single values along with a title and optional icon. Use R Markdown to publish a group of related data visualizations as a dashboard. The Layouts page includes a variety of sample layouts which you can use as a starting point for your own dashboards. Content after the separator will appear in a commentary sidebar to the right. You can define dashboard sections that don’t include a chart but rather include arbitrary content (text, images, equations, etc.). A number of other R packages provide cartogram algorithms, but the great thing about cartogram is that all the functions can take an sf (or sp) object as input and return an sf object. For example, this code creates a dashboard with two pages, each containing two charts: Note that in this example both pages use the default “columns” orientation. Flexible options for component layout are available and dashboards with many components can be organized into multiple pages. The code required for simple tables differs depending on whether you are building a static or dynamic (Shiny-based) flexdashboard. Develop and share web applications using the most popular package for R web apps. To define a page just use a level 1 markdown header (==================). In addition, some flexdashboard components have special behavior to adapt themselves to smaller mobile screens: By default R graphics are rendered twice, once at their natural fig.width and fig.height, and once at a mobile-optimized size (3.75 x 4.8 inches). “Frame 1”) will be used as navigation captions. Here is the navabar-inverse CSS for the default “cosmo” theme used by flexdashboard: https://github.com/thomaspark/bootswatch/blob/v3.3.5/cosmo/bootstrap.css#L4643-L4744. A wide variety of components can be included in flexdashboard layouts, including: Interactive JavaScript data visualizations based on htmlwidgets. For example, the following dashboard includes an embedded copy of the source code which can be viewed by clicking the “Source Code” button on the navigation bar: If you need to include additional narrative or explanation within your dashboard you can do so in the following ways: You can include content at the top of the page before dashboard sections are introduced. For example: Note that the base CSS styles are defined both the active Bootswatch theme as well as in the flexdashboard specific stylesheets found here: https://github.com/rstudio/flexdashboard/tree/feature/logo-and-favicon/inst/rmarkdown/templates/flex_dashboard/resources. with flexdashboard. The Data Table will use pagination (i.e. A simple table is ideal for smaller numbers of records (i.e. For example, the following specifies a navigation bar icon for each of two pages: You can specify icons for navigation bar items from three different icon sets: Storyboards are an alternative to the row and column based layout schemes described above that are well suited to presenting a sequence of data visualizations and related commentary. “#ffffff”, “rgb(100,100,100)”, etc.). You can customize the various CSS styles used in flexdashboard by including a stylesheet via the css option. install.packages("flexdashboard") To author a flexdashboard you create an R Markdown document with the flexdashboard::flex_dashboard output format. Here’s the definition of a two column dashboard with one chart on the left and two on the right: You can also choose to orient dashboards row-wise rather than column-wise, by specifying the orientation: rows option. However, if you’ve already provided prominent navigational links to pages you may wish to exclude them from the navigation bar entirely. The DT package (an interface to the DataTables JavaScript library) can display R matrices or data frames as interactive HTML tables that support filtering, pagination, and sorting. For example, here are three side-by-side sections each displaying a single value: Here is the code which was used to generate these value boxes: The valueBox function is called to emit a value and specify an icon (see Icon Sets below for details on available icons). Include a set of level 3 (###) dashboard components. R graphical output including base, lattice, and grid graphics. Sometimes you want to include one or more simple values within a dashboard. It has three required arguments: value, min, and max (these can be any numeric values). For example: By default, the flexdashboard navigation bar includes the document’s title, author, and date. For example: The logo will be placed at the far left of the dashboard navigation bar. should be seen by all readers) and the others provide secondary information that might be of interest to only some readers. You can use any chart created with standard R graphics (base, lattice, grid, etc.) Add sidebar attribute to the first column of the dashboard. When displaying on a mobile phone in portrait orientation the mobile size is used (this can be controlled via the fig_mobile option). You can find example uses of several of the more popular htmlwidgets in the htmlwidgets showcase and browse all available widgets in the gallery. By default, dashboards are laid out within a single column, with charts stacked vertically within a column and sized to fill available browser height. This specifies that the Shiny package will be used to handle reactive content. Tabular data (with optional sorting, filtering, and paging). Within static dashboards standard R graphics are also scaled (with aspect ratios preserved so there is no stretching or distortion). This section describes the layout algorithm and the various ways you can tweak its behavior. We would like to show you a description here but the site won’t allow us. You can do this by creating two identically titled sections and applying the {.mobile} class attribute to one of them. You can include links to social sharing services via the social option. Flexdashboard makes it particularly easy to create dashboards using R Markdown and a convention for how the headers affect the layout: Each level 1 header ( # ) begins a new page in the dashboard. This example is a variation of the single-column layout demonstrated above with a data-height attribute applied to the first chart: By default flexdashboard places 8 pixels of padding around the edges of charts. Install the flexdashboard package from CRAN as follows:. The Shiny page describes how to create dashboards that enable viewers to change underlying parameters and see the results immediately, or that update themselves incrementally as their underlying data changes. For example, the following dashboard has 4 pages, 2 of which are located on “Menu A” and two of which are located on “Menu B”: You can form links directly to dashboard pages using markdown link syntax: [Page 2]. It will support all but one of the features discussed in this article: dynamic tabs, which are the basis of the technique used in the example to drive the drill throughs. You can also choose to orient dashboards row-wise rather than column-wise by specifying the orientation: rows option. For mobile phones (any screen less than or equal to 768 pixels wide) flexdashboard uses special layout behavior. These themes are all based on the themes available in the R Markdown package (which are in turn based on Bootswatch themes). Use the theme option to specify an alternate theme: If you are looking for a theme that embeds well inside another content frame (e.g. To create a storyboard layout you do the following: Add the storyboard: true option to the dashboard. For example: Note that the second frame includes a data-commentary-width=400 attribute. We’ve also given the column a larger size via the data-width attribute to provide additional emphasis to Chart 1. Add a new code chunk {r data} where we will load and work with the data. For example, here is a set of 3 gauges: Here is the code used to generate these gauges: There are a few things to note about this example: The gauge function is used to output a gauge. In addition to these marker symbols, you can also use add_text() to encode data with on-graph text. For example: By default each page you define is given it’s own top level tab on the navigation bar. To use custom link text you can also create a link via the page’s anchor: [Page Two](#page-2). force bPaginate = TRUE). The package is not in the repositories you selected. Value boxes for highlighting important summary data. When creating static (non-Shiny) dashboards containing standard R graphics it’s critical to define knitr fig.width and fig.height values as close as possible to what they’ll actually be on the page. Each page you define will have its own top-level navigation tab. This can be accomplished by adding the {.hidden} attribute to the page you want to hide from the navigation bar. Rather, on mobile phone layouts: The Simple Table will display all available records; and. An interactive widget is also provided for previewing themes in real time. Flexible and easy to specify row and column-based layouts. The following code creates a storyboard with 3 frames: Note that the level 3 section titles (e.g. You can specify an optional symbol to be displayed alongside the value (in the example “%” is used to denote a percentage). The implication of this is that chart dimensions established via either knitr figure sizes or data-width and data-height attributes are used to establish relative sizes between charts within the same horizontal or vertical dimension as opposed to absolute sizes (this corresponds to the flex-grow and flex-shrink CSS properties). The third code chunk (“Spam per Day”) makes the background color of the value box dynamic using the color parameter. rbokeh, an interface to Bokeh, a powerful declarative Bokeh framework for creating web-based plots. Getting Started. In this case you can either add the .no-padding attribute to specify no padding at all or the data-padding attribute to specify a specific number of pixels. The title is simply the text after the level 3 (###) section heading. You can include a link to the dashboard’s source code using the source_code option. For example: Gauges display values on a meter within a specified range. For example, the following dashboard includes Twitter and Facebook links as well as a drop-down menu with a more complete list of services: The social option can include any number of the following services: “facebook”, “twitter”, “google-plus”, “linkedin”, and “pinterest”. The navigation bar for flexdashboard uses the navbar-inverse class for each of its themes. Within dynamic (Shiny) dashboards these charts are automatically sized to fit within their dashboard containers so long as they are wrapped within a call to renderPlot. This section describes layout behavior for various screen sizes as well as some guidelines for ensuring that your dashboards work well on smaller screens. This is appropriate for smaller datasets where scrolling provides a comfortable way of navigating through the data. If a gauge displays a value for which additional detail is available on another dashboard page you can enable navigation to the other page via the href parameter. The height of charts is determined in one of two ways depending on whether your dashboard is configured to fit itself into the vertical confines of the page (vertical_layout: fill) or to scroll (vertical_layout: scroll): For dashboards that fill the page the height of charts will be determined by the height of the browser, with vertically stacked charts splitting the available height evenly (unless overridden via the data-height attribute as described below). This enables them to fit into their layout container as closely as possible when the dashboard is laid out. For scrolling dashboards, the height of charts will be determined by the knitr fig.height option, which defaults to 5 inches (480 pixels). The Examples page includes several examples of flexdashboard in action (including links to source code if you want to dig into how each example was created). The notes are any text prefaced with > after the code chunk which yields the component’s output. My title for the dashboard is big. Available themes include: The “cosmo” theme is used when “default” is specified. By default the width of the commentary sidebar is 300 pixels, you can use data-commentary-width to modify this on a per-frame basis. If you do this, realize that themes define colors for many elements and states, so you should be careful to override all of the required elements. The nature of the charts within your dashboard (desired emphasis, visualization types, etc.)
