I think the OP does not realize that head() and tail() do not print anything. They extract the first or last values/rows and if they are not assigned to an object, they automatically go to print().
Redefining print.data.frame would also fix that problem. David L.

I see character strings left justified, e.g. x <- rep(c("a", "ab", "abc"), 7) prints as [1] "a" "ab" "abc" "a" "ab" "abc" "a" [8] "ab" "abc" "a" "ab" "abc" "a" "ab" [15] "abc" "a" "ab" "abc" "a" "ab" "abc" In a data frame, I do see it right justified: x 1 a 2 ab 3 abc etc. It is easy to change the printing of data frames: print.data.frame <- function(x, ..., right = FALSE) { base::print.data.frame(x, ..., right = right) } > data.frame(x) x 1 a 2 ab 3 abc Are there other examples you're seeing?
