stri_sort: Sorting¶
Description¶
This function sorts a character vector according to a locale-dependent lexicographic order.
Usage¶
stri_sort(str, decreasing = FALSE, na_last = NA, ..., opts_collator = NULL)
Arguments¶
|
a character vector |
|
a single logical value; should the sort order be nondecreasing ( |
|
a single logical value; controls the treatment of |
|
additional settings for |
|
a named list with ICU Collator’s options, see stri_opts_collator, |
Details¶
For more information on ICU’s Collator and how to tune it up in stringi, refer to stri_opts_collator.
As usual in stringi, non-character inputs are coerced to strings, see an example below for a somewhat non-intuitive behavior of lexicographic sorting on numeric inputs.
This function uses a stable sort algorithm (STL’s stable_sort
), which performs up to N*log^2(N) element comparisons, where N is the length of str
.
Value¶
The result is a sorted version of str
, i.e., a character vector.
