I am trying to run an optimization model and it crashes at different points each time. Seems to be related to a package, but not sure which one. I tried but can't find it. What do I do?
The version info is as below:
system x86_64, mingw32
svn rev 77560
version.string R version 3.6.2 (2019-12-12)
nickname Dark and Stormy Night
The crash log for today is as below. Only tried it once to avoid duplication and noise.
