Also,
formatC(3,width=3,flag='0')
formatC and sprintf are both referenced in the "See Also" part of the
format help page.

See ?sprintf
sprintf("%03d", 1:99)

Note the format specifies that the argument 1:99 should be formatted
with leading zeroes to fill a 3 character width output.
Importantly, note that the result is a character vector and not
numeric values, though you can coerce back to numeric with
?as.numeric.
