prevent rgl from opening window in package examples

I have several packages that make extensive use of rgl in documentation examples. Every time I do R CMD check, every such example opens a collection of rgl windows briefly, which is annoying.

Is there some rgl setting I can use in the .Rd files to suppress this behavior? Is there any downside to doing this?

Set the environment variable RGL_USE_NULL=TRUE and rgl won't try to open any windows.

This should be done outside of R, before running R CMD check. It can also be done inside R using Sys.setenv(RGL_USE_NULL = TRUE) before loading rgl if you don't want to see rgl displays during an interactive session.
