Thanks. I see it’s in SWIP 9.1.20 so I’ll do my final testing on thta.
The package actually contains two modules - clpBNR and clpBNR_utilities. I assume the install will include both.
Note: the last post on Sandboxing modules - #3 by ridgeworks discusses a minor change to library(simplex) to make its maximize/3 and minimize/3 accessible on SWISH. The fix is fairly simple and at some point I’ll try to generate a PR.
If this is the solution, I’ll give a hard pass. I’ll just add the inability to view the constraint network at the toplevel to list of things not supported on SWISH. It’s primarily a developer feature anyway, so there are a few of these on that list.
