Dear Duncan,

A while ago I added support in rgl to run on headless machines. Set

(It's also possible to use options(rgl.useNULL = TRUE) within R.
That's
no help to you, but is useful when embedding rgl plots in knitr
documents.)
Could I just check if this approach can be used to suppress example code
including rgl calls when it is running on CRAN as part of R CMD check? I
have a package that does not build on r-release-osx-x86_64-mavericks
because there appears to be a problem with rgl and the examples fail:
https://www.r-project.org/nosvn/R.check/r-release-osx-x86_64-mavericks/nat-00check.html
Of course I could put all the examples inside dontrun blocks, but I do
prefer to have them run.
Many thanks for any suggestions,
Greg.
