R help - May 2025 - Formatting zeroes with prettyNum

Dear list,

Have I stumbled upon a bug, or am I holding `prettyNum()` wrong? Please see
below.

Best,

Mikko
> prettyNum(0, zero.print = "- ", replace.zero = 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'
> 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'

Thank you.

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.
