I have an Optimization model in Excel that I am taking over to R now. Researched a bit and found an OMPR package that best suits my needs and looks very easy to work with.
Now when I actually reach the end point to solve the problem, I'm lost on how I would actually pick up CPLEX/GLPK solver? I tried installing the ROI.Plugin.cplex but it errors out saying I don't have CPLEX installed
Do these solvers need to be installed somewhere on the linux machine and R would need to know that path through env var or something? Appreciate any guidance on this. Essentially duplicating what the example is doing on this page would be a way of running into the issue https://dirkschumacher.github.io/ompr/
Thank you
