I am having the same problem as this and this.
I have installed R and rstudio through a conda environment which included r-rgl. I am now trying to install a package within R that requires rgl. However, calling library(rgl) gives the error
Error: package or namespace load failed for ‘rgl’:
package ‘rgl’ was installed by an R version with different internals; it needs to be reinstalled for use with this R version
I have tried to install rgl from within R, but then I get this message:
checking for X... no
configure: error: X11 not found but required, configure aborted.
ERROR: configuration failed for package ‘rgl’

Warning in install.packages :

The solution to the last error seems to be installing XQuartz in Mac, but I had it installed before. So I tried specifying install.packages("rgl", INSTALL_opts = "--with-libpng-prefix=/usr/X11/") but I still get the error above. Any suggestions? I'm quite lost now...
TL;DR: how do I connect my XQuartz installation with each conda environment that I create?
