lpSolveAPI

The lpSolveAPI package was created by Kjell Konis, I currently maintain the package. lpSolveAPI provides an interface to lp_solve which was last updated 2016. Therefore if you don't need callbacks it is recommended to use ROI (https://cran.r-project.org/package=ROI, https://roi.r-forge.r-project.org/) instead.
