Installing

Use devtools to install this package from GitHub. Make sure to build vignettes!

# install.packages("devtools")
devtools::install_github("benet1one/EasyLP", build_vignettes = TRUE)

Getting Started

First, create the problem by using easylp$new(). Then define variables with $var(), set the objective function with $min() or $max(), and constraint the problem with $con(). Then, solve the problem and print the results.

library(easylp)
lp <- easylp$new()
lp$var("x")
lp$var("y")
lp$max(x + y)
lp$con(
    x + 2*y <= 3,
    y >= 3*x - 2
)

lp$solve()
lp
