I’ve removed XQuartz (again), and installed R and R-app from MacPorts. The R install warned me that Clang compilers provided by Xcode do not support OpenMP. Some R packages using OpenMP may require additional flags in the Makevar file (e.g. data.table) to build. Please consult package documentation.
I install.package’d data.table without whinging, then did the same for rgl. It built, but when I loaded the library, I was informed that This build of rgl does not include OpenGL functions. Looking around for mentions of OpenGL, I couldn’t se anything that looked like an OpenGL library. Any suggestions?
