this is the problem. At least one package needs re-installing. And
indeed RKWard is to blame for handling the case of updated R version,
badly, here.

Solutions:
1) Settings->Manage R packages and Plugins->Install / Update /
Remove->Update all packages. Likely but not guaranteed to fix the
problem, and may potentially mean re-installing quite a number of
packages.
2) Re-install package "minqa", only. Potentially the fastest solution,
but other packages could be broken, too. Rinse and repeat for these.
3) Safest: Move /Users/user/.rkward/library/ out of the way, and
install the packages you need from scratch.

I suggest you try method 2, first, then method 3.
