I've not had enough experience in perl to have used exit, but this is my guess at what is wanted: spend.time <- function(i) { i <- 1 while(i < 10){ print(i) if (i == 5) break if (i == 7) stop("Is this an error?") i <- i + 1 } } > spend.time(7) [1] 1 [1] 2 [1] 3 [1] 4 [1] 5 > We don't get as far as 7, so the error message doesn't appear. However, if the break is put after 7, an error has already occurred, as in: spend.time2 <- function(i) { i <- 1 while(i < 10){ print(i) if (i == 9) break if (i == 7) stop("Is this an error?") i <- i + 1 } } > spend.time2(7) [1] 1 [1] 2 [1] 3 [1] 4 [1] 5 [1] 6 [1] 7 Error in spend.time2(7) : Is this an error? > HTH -- Patrick Connolly HortResearch Mt Albert Auckland New Zealand Ph: +64-9 815 4200 x 7188 ~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~ I have the world`s largest collection of seashells.
