[Rd] missing IntegerFromString()

Thanks to everybody who responded to my question.
asInteger(coerceVector(x,INTSXP)) indeed does what I need. I guess there
is a lot I don't understand about type coercion, as I would not have
expected it to work.

I think you want asInteger (which calls IntegerFromString).  This is
in RHOME/include/Rinternals.h
