Let me point out the following extract from R-exts.R, *in the same directory*
## ----- outer products example -----
out <- function(x, y) .Call("out", as.double(x), as.double(y))
x <- as.double(1:3); names(x) <- letters[x]
# so as not to lose names
out <- function(x, y) .Call("out", x, y)
so the lack of clarity is not in the R sources (which do at least get the
function names right).
