stri_order {stringi} | R Documentation |
stri_order determines a permutation which rearranges strings into an ascending or descending order. stri_sort sorts the vector according to a lexicographic order.
stri_order(str, decreasing = FALSE, na_last = TRUE, ..., opts_collator = NULL) stri_sort(str, decreasing = FALSE, na_last = NA, ..., opts_collator = NULL)
str |
a character vector |
decreasing |
a single logical value; should the sort order

in stringi, refer to stri_opts_collator
.
These functions use 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
.
Interestingly, our benchmarks indicate that stri_order
is most often faster that R's order
.
For stri_order
, an integer vector that gives the sort order
is returned.
For stri_order
, you get a sorted version of str
,
i.e. a character vector.
