Installing Rgdal

What follows are instructions to install rgdal for use within R 3.6.3, and gdal 3.0.4. The following commands will need to be run on one of our login nodes:

# 1. start with a clean slate!
module purge

# 2. load the dependent modules for rgdal
module load R/3.6.3 proj/6.1.0 gdal/3.0.4

# 3. setup the PROJ environment
export PKG_CONFIG_PATH=/packages/PROJ/6.1.0/lib/pkgconfig

# 4. start R
R

# 5. Install the rgdal package
install.packages(c('rgdal'),repos = "http://cran.case.edu", configure.args=c("--with-proj-include=/packages/PROJ/6.1.0/include","--with-proj-lib=/packages/PROJ/6.1.0/lib"))

# 6. UPDATE: if previous step results in an error with
# "proj_create_crs_to_crs_from_pj" then you will need to
# force the installer to use an older version, by doing
# the following:
packageurl <- "https://cran.r-project.org/src/contrib/Archive/rgdal/rgdal_1.4-8.tar.gz" install.packages(packageurl, repos=NULL, type="source")
