Hi, This was surprising to me and does not appear to be documented in ?str. After reading ?strwrap, I see that the problem is that "Whitespace ... in the input is destroyed". However, I thought I'd mention it because I'm not sure it is intended behavior for str().
I have a list, and the names of the list have a variable number of characters. > x <- list(A=1:10, ABCDEF=LETTERS[1:10]) > str(x) List of 2 $ A : int [1:10] 1 2 3 4 5 6 7 8 9 10 $ ABCDEF: chr [1:10] "A" "B" "C" "D" ... The above looks as expected in my R session (although it looks a little different when I paste it into this e-mail). There are 5 spaces between the A and the colon. i.e. there are the same number of characters before the colon for both components of the list. However, if I use strict.width="wrap", the colons (:) are no longer aligned > str(x, width=20, strict.width='wrap') List of 2 $ A : int [1:10] 1 2 3 4 5 6 7 8 9 10 $ ABCDEF: chr [1:10] "A" "B" "C" "D" ... Notice that now there is only 1 space between the A and the colon instead of 5. It looks like the call to strwrap() is causing the issue (i.e. destroying whitespace as it is documented to do). This is fine: > cat(capture.output(utils:::str.default(x)), sep="\n") List of 2 $ A : int [1:10] 1 2 3 4 5 6 7 8 9 10 $ ABCDEF: chr [1:10] "A" "B" "C" "D" ... This isn't: > cat(strwrap(capture.output(utils:::str.default(x)), 20), sep="\n") List of 2 $ A : int [1:10] 1 2 3 4 5 6 7 8 9 10 $ ABCDEF: chr [1:10] "A" "B" "C" "D" ... I'm wondering if it would be possible for the call to strwrap() to not include `indent.str`, `comp.str`, or the component names; then those things could be added afterwards. Although, I guess that probably requires adding an argument to str.default to control whether names are printed or not.
