Thanks for looking. I provided commit rights on R-forge, so if you see 
things that need fixing, please do so!

(Yosemite should have been Mavericks, of course). The examples are on the 
help pages, so running R inside GRASS 7 something like:

library(spgrass)
example(execGRASS)
example(gmeta)
example(spgrass)
example(readRAST)
example(readVECT)

interactively would be a possibility.

I guess that the package will move to nc_basic to align better with GRASS 
7.

Best wishes,

Roger
