# Map libraries
# You must install geos (http://trac.osgeo.org/geos/) and
# gdal (http://www.gdal.org/) first.
# OS X: `brew install geos gdal`
# Ubuntu: sudo apt-get install libgeos-dev libgdal-dev libproj-dev
# Then install these packages from source
# install.packages(c("rgeos", "rgdal"), type="source")
