[R] Formatting zeroes with prettyNum

[Marttila Mikko]

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) :
