I work almost exclusively in R and Rstudio, and have found it to be an excellent ecosystem for data analysis and OR, including discrete event simulation, Monte Carlo simulation, MILP, and the Traveling Salesman Problem. The ONLY gap I see is, no library for the Vehicle Routing Problem and variants.
Anybody know of a VRP package in R? I may need to undertake writing functions implementing VRP if I can't find a ready package.
