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'.
