Hello, I have been working on adding an option for my users to use integer programming (a method of optimization) to enhance the results of a function in my package. There are several R packages on CRAN that perform integer programming, including Rglpk and Rsymphony. However, there is a commercial solver called Gurobi that dramatically outperforms all open-source solvers, and it comes with an R interface through the gurobi package. I want to allow my users to use Gurobi to perform the package actions.
A potential issue is that the gurobi package is not on CRAN; it comes with an installation of the Gurobi software, which requires a license. I am not sure how to add gurobi to my Description file to satisfy CRAN's requirements. In CMD CHECK, I get the warning that the package is not available for checking. However, I have noticed some other packages do use gurobi just as I want to (i.e., as an option), such as CVXR <https://cran.r-project.org/package=CVXR> and designmatch <https://cran.r-project.org/package=designmatch>, which put gurobi in Enhances (though I would have thought it would belong in Suggests). It seems that neither of these packages passes the CRAN checks, though. I'm wondering what the best practices are for including gurobi in my package. To be clear, its use is optional and the package can be functional without it, but it greatly enhances performance so I want my users to be able to use it. Thank you!
