How to perform natural (lexicographic) sorting in R? [duplicate]

by

I don’t think “alphanumeric sort” means what you think it means.

In any case, looks like you want mixedsort, part of gtools.

> install.packages('gtools')
[...]
> require('gtools')
Loading required package: gtools
> n
[1] "abc21"  "abc2"   "abc1"   "abc01"  "abc4"   "abc201" "1b"     "1a"    
> mixedsort(n)
[1] "1a"     "1b"     "abc1"   "abc01"  "abc2"   "abc4"   "abc21"  "abc201"
