a mild problem here with nested R stuff:

Gretl definitely expects a return value from an R function, so
R.ckR1() is going to fail regardless of the calling context.
Well, maybe that can be relaxed. We accept "void" hansl functions
that don't return anything (just print stuff, presumably), so we can
accept void R functions too -- that's now in git. But I'd be
surprised if there's much call for such functions.
