naturalfactor

a character vector whose elements might be appeared in <code>x</code>.

levels

logical flag that determines whether the factor is ordered.

ordered

arguments that are passed to <code>factor</code> function.


<code>naturalfactor</code> creates a factor with levels in natural order.


Provides functions related to human natural ordering.
It handles adjacent digits in a character sequence as a number so that
natural sort function arranges a character vector by their numbers, not digit
characters. It is typically seen when operating systems lists file names. For
example, a sequence a-1.png, a-2.png, a-10.png looks naturally ordered because 1
< 2 < 10 and natural sort algorithm arranges so whereas general sort algorithms
arrange it into a-1.png, a-10.png, a-2.png owing to their third and fourth
characters.
