[R] Formatting zeroes with prettyNum

[Howard, Tim G (DEC)]

You fed it two characters, "dash" and "space" and it only wanted one character so it truncated to the first character and warned you that that's what it did.

If you had your space before the dash, it would have used that as your replacement character

> prettyNum(0, zero.print = " - ", replace = TRUE)

[1] " "

Warning message:
In .format.zeros(x, zero.print, replace = replace.zero) :
  'zero.print' is truncated to fit into formatted zeros; consider 'replace=TRUE'


When zero.print is only one character, it doesn't give a warning.
