paste <- function (..., sep = " ", collapse = NULL)
.Internal(paste(list(...), sep, collapse))
paste0 <- function(..., collapse = NULL)
.Internal(paste0(list(...), collapse))
##=== Could we extend paste(.) to (optionally) accept a
## 2-vector for collapse ? With the following functionality
##- paste.extra <- function(r, collapse=c(", "," and ")) {
##- n <- length(r)
##- if(n <= 1) paste(r)
##- else
##- paste(paste(r[-n],collapse=collapse[1L]),
##- r[n], sep=collapse[min(2,length(collapse))])
##- }
