Either change your script by adding print(...) calls where you want to see something printed or change the call to source() by adding print.eval=TRUE or echo=TRUE. E.g.,
> cat(file = tf <- tempfile(), "head(10:1)\ntail(letters)\nx <- gamma(0:4)\nx\n") > source(tf) Warning message: In gamma(0:4) : NaNs produced > source(tf, print.eval=TRUE) [1] 10 9 8 7 6 5 [1] "u" "v" "w" "x" "y" "z" [1] NaN 1 1 2 6 Warning message: In gamma(0:4) : NaNs produced > source(tf, echo=TRUE, print.eval=TRUE) > head(10:1) [1] 10 9 8 7 6 5 > tail(letters) [1] "u" "v" "w" "x" "y" "z" > x <- gamma(0:4) > x [1] NaN 1 1 2 6 Warning message: In gamma(0:4) : NaNs produced > Calling options(warn=1) before calling source() will keep the warnings near the lines that caused them.
