stri_trans_char: Translate Characters

In stringi: Fast and Portable Character String Processing Facilities

Translate Characters

Description

Translates Unicode code points in each input string.

Usage

stri_trans_char(str, pattern, replacement)

Arguments

str	character vector
pattern	a single character string providing code points to be translated
replacement	a single character string giving translated code points

Details

Vectorized over str and with respect to each code point in pattern and replacement.

If pattern and replacement consist of a different number of code points, then the extra code points in the longer of the two are ignored, with a warning.

If code points in a given pattern are not unique, the last corresponding replacement code point is used.

Time complexity for each string in str is O(stri_length(str)*stri_length(pattern)).

Value

Returns a character vector.
