R Markdown renders to four presentation formats: beamerpresentation - PDF presentations with beamer ioslidespresentation - HTML presentations with ioslides slidypresentation - HTML presentations with slidy powerpointpresentation - PowerPoint presentation revealjs::revealjspresentation - HTML presentations with reveal. ![]() You can find example uses of several of the more popular htmlwidgets in the htmlwidgets showcase and browse all available widgets in the gallery. There are over 30 packages on CRAN which provide htmlwidgets. VisNetwork, an interface to the network visualization capabilities of the vis.js library. Highcharter, a rich R interface to the popular Highcharts JavaScript graphics library. Rbokeh, an interface to Bokeh, a powerful declarative Bokeh framework for creating web-based plots. Plotly, which via its ggplotly interface allows you to easily translate your ggplot2 graphics to an interactive web-based version. Leaflet, a library for creating dynamic maps that support panning and zooming, with various annotations like markers, polygons, and popups.ĭygraphs, which provides rich facilities for charting time-series data and includes support for many interactive features including series/point highlighting, zooming, and panning. Charts based on htmlwidgets are ideal for use with flexdashboard because they can dynamically re-size themselves, so will nearly always fit perfectly within the bounds of their flexdashboard containers. How to start The first step is to get R and RStudio, and install the package rmarkdown with the code install.packages('rmarkdown') In the last versions you can directly create presentations going to File -> New File -> R Presentation. The htmlwidgets framework provides high-level R bindings for JavaScript data visualization libraries. In fact, the tabset examples above use header attributes in two places: Column is a valid set of header attributes that you might use in flexdashboard. However, if you want to use a different complete ggplot2 theme (e.g., theme_minimal() instead of the default theme_gray()), you should set the theme globally with ggplot2::theme_set().Flexdashboard relies heavily on pandoc’s header attribute syntax and you’ll see the syntax referenced throughout our documentation. Uses the background, foreground, and accent colors to construct a new default for scale_fill_continuous() (and scale_color_continuous()).Īs you’ll learn in the custom themes article, you can always override the defaults set by thematic by using plot-specific code (i.e., by adding theme() elements to the plot).It just so happens that this darkly theme colors type="tabs" the same as hyperlinks, but type="pills" is colored differently. An alternate approach would be to make the change in the stylesheet of the theme. These themes are prebuilt and unless one of them already have the Sunskit gradient set, the outcome won't be what you desire. The accent color comes from the hyperlink color of the plot’s HTML container. 1 Answer Sorted by: 0 Changing the theme in YAML will not achieve what you intend to do. ![]() Sets new geom_*() defaults using the new foreground (in this case, geom_point()’s color) and accent color (in this case, geom_smooth()’s color).Now, if we change our tabsetPanel() from type="pills" to type="tabs" and look at a couple other ggplot2 examples, we can see that thematic_shiny() does a few more things: Set a new color-blind safe default for scale_color_discrete() (and scale_fill_discrete()).Set new ggplot2::theme()-ing defaults based on the background and foreground colors (as well as appropriate mixtures of these colors for the panel background).Thematic_shiny ( ) shinyApp ( ui, server )įrom the ggplot2 example above, we can see thematic_shiny() has done the following for us: ![]()
