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
Questions:
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
