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 wind or rain.

In order to install rgdal:

1. 1. Load the R, proj, and gdal modules required for rgdal.
      [abc123@wind ~]$ module load R/3.6.3 proj/6.1.0 gdal/3.0.4
   2. Export the PKG_CONFIG_PATH environment variable.
      [abc123@wind ~]$ export PKG_CONFIG_PATH=/packages/PROJ/6.1.0/lib/pkgconfig
   3. Start R.
      [abc123@wind ~]$ R
   4. 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"))

Troubleshooting

If you receive the proj_create_crs_to_crs_from_pj error, then you will need to force the installer to use an older version. This can be done inside an R shell by executing the following commands:
> packageurl <- "https://cran.r-project.org/src/contrib/Archive/rgdal/rgdal_1.4-8.tar.gz"
> install.packages(packageurl, repos=NULL, type="source")
