I am getting this error everytime I run library(matlib): Error: package or namespace load failed for ‘matlib’: .onLoad failed in loadNamespace() for 'rgl', details: call: rgl.init(initValue, onlyNULL) error: OpenGL is not available in this build

library(matlib)
Registered S3 methods overwritten by 'rgl':

Warning:    Loading rgl's DLL failed. 
    This build of rgl depends on XQuartz, which failed to load.

  • What OS and R version are you using? How did you install R? Did you read the discussion mentioned in the error message? https://stackoverflow.com/a/66127391/2554330 – MrFlick Sep 13 '21 at 05:34
  • Have you installed [XQuartz](https://www.xquartz.org/)? – Roland Sep 13 '21 at 06:19

    If you run `Sys.setenv(RGL_USE_NULL=TRUE)` before calling `library(matlib)`, you'll probably get past this error. Graphs using the `rgl` package won't display in R, but you can get them to display in a browser: see `?rgl::rglwidget`. – user2554330 Sep 13 '21 at 09:20

Running this before library(matlib) worked for me:

Sys.setenv(RGL_USE_NULL=TRUE)
