UPDATE: see more recent version of this post here.
I wanted to play around with the new
sf package, which requires the latest GDAL (>= 2.0.0), GEOS (>= 3.3.0), and PROJ.4 (>= 4.8.0).
However, the version of GDAL installed via
brew is 1.11.4, so I needed to update to the latest version and reinstall a few R packages in order to get
sf to work on macOS.
## unlink the previous GDAL version brew unlink gdal ## update GDAL to the latest version (2.1.2) brew tap osgeo/osgeos4mac brew install gdal2 brew link --force gdal2
(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
