as_factor | R Documentation |
Compared to base R, when x
is a character, this function creates
levels in the order in which they appear, which will be the same on every
platform. (Base R sorts in the current locale which can vary from place
to place.) When x
is numeric, the ordering is based on the numeric
value and consistent with base R.
