sprintf("%03d", 2)
formatC(2, width=3, flag="0")

[1] "002"

Hello R-helpers,
I have a problem with formatting a single number to show leading zeros. For
example, I want "2" displayed as "002".
I hope you meant that you want 2, not "2", so displayed. Otherwise you
need as.numeric("2") here.
My numbers have 1 to 3 digits and I would like them all to display 3 digits
for printing. I know I could use "paste" in a loop with several "if"s, but I
was wondering if there is a single function that can do this.
I have tried "format", "prettyNum" and "formatC" back and forth, but these
functions don't seem to be able to display leading zeros. Please help.
You will find studying the help more productive than 'tried ... back and
forth'.
