[R-sig-Geo] R GRASS bindings Mac OSX

[Don MacQueen]

Well, it's easy to find the rgdal package, it's on CRAN. However, as 
noted there, rgdal is not available from CRAN in binary form for OS 
X, so you have to build it from source. In order to do that you first 
need to install gdal and proj. CRAN is pretty clear on these 
dependencies. It even says where to get gdal and proj from. (I 
recently installed these for R 2.8.0 on 10.5.5, and it was very 
straightforward)

spgrass6 I can't help you with, other than to note that according to 
CRAN, its only dependency is rgdal, so it should go easily once you 
have rgdal. But I haven't done so myself.

If you need to learn how to build packages from source on OS X, and 
they are packages that have C source code (as these do) then you'll 
need to visit the R for Mac OS X FAQ, also reachable through CRAN.
