stringi (version 1.4.3)

stri_sort: Sorting

Description

The function sorts a character vector according to the locale-dependent lexicographic order.

Usage

stri_sort(str, decreasing = FALSE, na_last = NA, ...,
  opts_collator = NULL)

Arguments

str

a character vector

decreasing

a single logical value; should the sort order be nondecreasing (FALSE, default, i.e., weakly increasing) or nonincreasing (TRUE)?

na_last

a single logical value; controls the treatment of NAs in str. If TRUE, then missing values in str are put at the end; if FALSE, they are put at the beginning; if NA, then they are removed from the output

...

additional settings for opts_collator

opts_collator

a named list with ICU Collator's options, see stri_opts_collator, NULL for default collation options

Value

The result is a sorted version of str, i.e., a character vector.

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 perhaps non-intitive 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.
