Dear All,
This question sounds very simple but I don't know where I am wrong. I just want
to pad leading zeros in some string, for example, "123" becomes "00123". What
is wrong if I do following?
> sprintf("%05s", "123")
[1] " 123"
It didn't return "00123", instead it padded with 'blank'.
Thank you for your help in advance.
