htmlwidgets for R

Overview

The htmlwidgets package enables you to use JavaScript visualization libraries like Leaflet, Plotly, dygraphs, and threejs directly from R.

If you are using the Knitr engine with Quarto this is a great way to incorporate interactivity without learning JavaScript or requiring a Shiny Server to view your document.

Usage

Including htmlwidgets within a Quarto document is as easy as including an R plot. For example, here is how we embed a Leaflet map:

```{r}
library(leaflet)
leaflet() %>%
  addTiles() %>%  # Add default OpenStreetMap map tiles
  addMarkers(lng=174.768, lat=-36.852, popup="The birthplace of R")
```

Warning: package 'leaflet' was built under R version 4.1.2

Layout

You can also use layout options with htmlwidgets. For example, here we provide a custom layout to arrange three dygraph time series plots:

```{r}
#| layout: [[1,1], [1]]
library(dygraphs)
dygraph(fdeaths, "Female Deaths")
dygraph(mdeaths, "Male Deaths")
dygraph(ldeaths, "All Deaths")
```

See the article on Figures for additional documentation on custom layouts.
