OK, I realize I'm hacking away in R in a manner that was not intended, but I found this interesting behaviour nonetheless, and I am not sure whether this was intended to be so or not.
> x <- list(1:3,1:3,1:3) > r1 <- do.call(paste,x) # the correct way > sapply(x,typeof) [1] "integer" "integer" "integer" > r2 <- .Internal(paste(x,sep=" ",collapse=NULL)) > sapply(x,typeof) [1] "character" "character" "character" So although I don't change x explicitly, after the call to .Internal(paste(...)) it suddenly is a list of characters instead of integers. Is this supposed to happen? (Normally .Internal(paste(...)) takes an anonymous list(...) as argument, so it might very well be the intended way of working.)
