GLPK/R

R is a free software environment for statistical computing and graphics. The R project is responsible for R. Packages for R are provided by the Comprehensive R Archive Network (CRAN). R is cross-platform and supported on Windows, MacOS X, and Linux.

In addition, R scripts (as can gnuplot scripts) can be use to process GLPK output directly, without the use of dedicated R packages.

Rglpk
Package Rglpk is provided by CRAN &mdash; which also contains the reference manual.

To install from repository within R: install.packages("Rglpk") To install from local archive within R: install.packages("Rglpk_0.6-3.tar.gz", repos = NULL, type="source") Debian-based Linux users can also install Rglpk via the Debian package r-cran-rglpk. But it would pay to check on currency.

Rglpk provides two functions:


 * Rglpk_read_file reads a linear problem from a file in either of the following formats: fixed MPS, free MPS, CPLEX, and GMPL.
 * Rglpk_solve_LP solves a linear and mixed linear problems.

The following commands solve a problem provided in GMPL file /home/user/test.mod library(Rglpk) x <- Rglpk_read_file( "/home/user/test.mod", type = "MathProg", verbose = TRUE) Rglpk_solve_LP(x$objective, x$constraints1, x$constraints2, x$constraints3, x$bounds, x$types, x$maximum)

glpkAPI
The package glpkAPI has not been maintained since 2015.

glpk
The deprecated package glpk has been archived by CRAN. It was based on GLPK 4.8 and never updated since 2006.
