[R-pkg-devel] how to make "r-release-osx-x86_64-mavericks" machine support rgl 3D plots

Dear all

I have a package(forestFloor) which produces an test error when built on the "r-release-osx-x86_64-mavericks" machine. I'm quite sure it's due to Xquartz(or similar) graphical resources have to be installed for 3D plotting. I tried with no luck, to screen the source code of ~15 other packages importing rgl to get some inspiration. Most packages did not run any rgl examples or tests.

See the error message below

1. I there a fix for "r-release-osx-x86_64-mavericks" machine? Could I e.g. specify Xquartz to be installed?
2. Should I in general just assume no OSX user has installed Xquartz and link to a OSX install-guide from source in description file?
3.  Can I in general test builds on "r-release-osx-x86_64-mavericks" machine somehow without spamming CRAN with submissions?

Thanks in advance
