Installing rgdal on OSX
This is actually really easy to do, but most of the google hits I came across were old (from 2010) or horribly complex (building gdal and proj4 from source then building rgdal itself).
First, this assumes you already have homebrew installed 1. If not, see
http://brew.sh/ for the one-liner terminal install.
Next, install gdal:
brew install gdal
Then open RStudio (for some reason it didn’t work using R in the terminal…) and install the package from source:
install.packages("rgdal", type="source")
That’s it. Seriously easy.
Update: fixed typos in brew commands
