regexprep: Replace string using regular expression

In pracma: Practical Numerical Math Functions

Replace string using regular expression

Description

Replace string using regular expression.

Usage

regexprep(s, expr, repstr, ignorecase = FALSE, once = FALSE)

Arguments

s	Single character string.
expr	Regular expression to be matched.
repstr	String that replaces the matched substring(s).
ignorecase	logical, whether to ignore case.
once	logical, shall only the first or all occurences be replaced.

Details

Matches the regular expression against the string and replaces the first or all non-overlapping occurrences with the replacement string.

The syntax for regular expression has to be PERL-like.

Value

String with substrings replaced.

Note

The Matlab/Octave variant allows a character vector. This is not possible here as it would make the return value quite complicated.
