OS X solution... was Re: rgdal functions: spTransform and CRS not working
I apologise for not following up in-thread, as I used to use Gmane to reply to postings read digested before its (hopefully temporary) demise. The problem is that the CRAN OSX binaries for rgdal are shipping without two key folders, proj/ and gdal/. Until we get it fixed, please see if you can download the equivalent Windows binary package: https://cran.r-project.org/bin/windows/contrib/3.3/rgdal_1.2-5.zip unzip it (do not install it), and copy the proj/ and gdal/ folders with their contents to the folder shown (in R) by: system.file("", package="rgdal") For OSX-specific questions like this, you could try R-sig-mac, for spatial data R-sig-geo. Always show the output of sessionInfo() when reporting issues.
