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
