Does .C duplicate unnecessary arguments? For instance fit<- .C("xxx", as.integer(n), x, y, z=double(15))The first and fourth arguments would have NAMED = 0. Is my guess that .C won't make yet one more (unnecessary) copy correct?
.C's internals (do_dotcode) does not know about NAMED. It duplicates (unless DUP=FALSE).
Use .Call if you want to control duplication.
