## Installing the R Package

To begin, you'll need to install the Gurobi package in R. The R command for doing this is:

install.packages('<R-package-file>', repos=NULL)

The R package file can be found in the <installdir>/R directory of your Gurobi installation. For a default installation of Gurobi 9.0.1, the command would be:

install.packages('/opt/gurobi901/linux64/R/gurobi_9.0-1_R_3.6.1.tar.gz', repos=NULL)

You will need to adjust the path to match your installation directory and version.

You will need to be careful that the R binary and the Gurobi package you install both use the same instruction set. To use the Gurobi R package, you will need to use the 64-bit version of R.

If you are using R from RStudio Server, and you get an error indicating that R is unable to load the Gurobi DLL or shared object, you may need to set the rsession-ld-library-path entry in the server config file. Please consult the RStudio documentation for more information.
