Installing the R package
To use our R interface, you'll need to install the Gurobi package in your local R installation. The R command for doing this is:
install.packages('<R-package-file>', repos=NULL)
The Gurobi R package file can be found in the <installdir>/R
directory of your Gurobi installation
(the default <installdir> for Gurobi 7.5.2 is /opt/gurobi752/linux64 for Linux,
c:\gurobi752\win64 for 64-bit Windows, and /Library/gurobi752/mac64 for Mac).
You should browse the <installdir>/R directory to find
the exact name of the file for your platform
(the Linux package is in file
gurobi_7.5-2_R_x86_64-pc-linux-gnu.tar.gz,
the Windows package is in file
gurobi_7.5-2.zip, and the Mac package is in file
gurobi_7.5-2.tgz).
You will need to be careful to make sure that the R binary and the Gurobi package you install both use the same instruction set. For example, if you are using the 64-bit version of R, you'll need to install the 64-bit version of Gurobi, and the 64-bit Gurobi R package. This is particularly important on Windows systems, where the error messages that result from instruction set mismatches can be quite cryptic.
To run one of the R examples provided with the Gurobi distribution,
you can use the source command in R. For example, if you
are running R from the Gurobi R examples directory, you can say:
> source('mip.R')
If the Gurobi package was successfully installed, you should see the following output:
[1] 'Solution:' [1] 3 [1] 1 0 1
