As an update to an earlier post, here’s how to use the latest versions of GDAL/PROJ with R spatial packages.
brew install pkg-config brew install gdal
(Re)install R spatial packages
Next, we need to install a few packages from source in order to use the new GDAL libraries:
## (re)install spatial packages from source install.packages(c("rgeos", "sf", "sp"), type = "source") ## rgdal requires some additional configuration to build correctly: ## based on http://stackoverflow.com/a/26836125/1380598 install.packages("rgdal", type = "source", configure.args = c("--with-proj-include=/usr/local/include", "--with-proj-lib=/usr/local/lib")) library(rgdal) ## confirm the GDAL version being used
