I'm afraid I am missing something. In my R function (call it "foo", say) I am doing something like
foo <- function() { ... .C("bar", ..., res=integer(n), ...)$res } but I don't know the "n" to use; that is determined inside my C function "bar". Is there a way around this? I'm sorry to be thick on this. Too many decades of C have made me love pointers too much, I reckon. Dirk Eddelbuettel wrote: > > > You want R_alloc().
