[R-pkg-devel] how to make "r-release-osx-x86_64-mavericks" machine support rgl 3D plots
I placed in top of all test scripts: if(!interactive()) Sys.setenv(RGL_USE_NULL=TRUE) #disable RGL for headless machines on 3) I guess I could build and test the github version of package on travis.ci in a OSX environment Many thanks for the help PS "What happens when you squeeze grapes? -they wine a lot"

Next time someone complains that "whining doesn't help", I'll send them to
this thread. Setting
Sys.setenv("RGL_USE_NULL"="TRUE") # Duncan Murdoch on r-package-devel on 12 Aug 2015
works wonderfully. I should have whined earlier ...
Thanks, Duncan!
