XQuartz and xorg-server

[Peter West]

I tried specifically building rgl from source. The source is available at https://cran.r-project.org/src/contrib/rgl_0.104.16.tar.gz.

In R.app console, remove rgl package.

> remove.packages(“rgl”)
> install.packages(<path-to-source.tar.gz>, repos = NULL, type = “source”)

It doesn’t find X, so it skips OpenGL; configure in the source needs tinkering.
