R-CMD-check Codecov test coverage

This is the project directory for the r3js, a package to provide R and javascript functions to allow WebGL-based 3D plotting in R using the three.js javascript library. Simple interactivity through roll-over highlighting and toggle buttons is also supported.

Plots are built as html widgets, using the RStudio viewer panel to display the plots interactively. Plots can also be exported using the functions provided in the htmlwidgets package.


You can install the development version from GitHub with:

# install.packages("devtools")


Generally, r3js works by generating an object containing the plotting data and then continuously updating it as new features are added to the plot (similar to plotly). For a simple 3D scatterplot however, the plot3js function handles all of the plotting setup for you. Plotting syntax is intended to be similar to the base plotting functions in R, and that used in the RGL package.

Several ways to add interactivity to plots are currently supported, namely labels, highlighting on mouse roll-over, and toggle buttons.

Using the possibilities together you can create plots like the one below.
