Ranking
This function ranks each string in a character vector according to a
locale-dependent lexicographic order.
It is a portable replacement for the base xtfrm function.
stri_rank(str, ..., opts_collator = NULL)
str |
a character vector |
... |
additional settings for |
opts_collator |
a named list with ICU Collator's options,
see |
Missing values result in missing ranks and tied observations receive the same ranks (based on min).
For more information on ICU's Collator and how to tune it up
in stringi, refer to stri_opts_collator.
The result is a vector of ranks corresponding to each
string in str.
