mgrep: Search strings for multiple patterns

In twolodzko/twextras: twextras

Description

Search strings for multiple patterns

Usage

mgrep(patterns, x, ignore.case = FALSE, perl = FALSE, value = FALSE,
  fixed = FALSE, useBytes = FALSE, invert = FALSE, list = FALSE)

mgrepl(patterns, x, ignore.case = FALSE, perl = FALSE, fixed = FALSE,
  useBytes = FALSE, action = "list")

Arguments

patterns	character string containing a regular expression (or character string)
x	character vector
ignore.case	if FALSE, the pattern matching is case sensitive and if TRUE, case is ignored during matching
perl	logical. Should perl-compatible regexps be used?
value	if FALSE, a vector containing the (integer) indices of the matches determined by grep is returned, and if TRUE, a vector containing the matching elements themselves is returned
fixed	logical. If TRUE, pattern is a string to be matched as is. Overrides all conflicting arguments
useBytes	logical. If TRUE the matching is done byte-by-byte rather than character-by-character.
invert	logical. If TRUE return indices or values for elements that do not match.
list	if TRUE list all matches
action	function for aggregating matches, e.g. all, any, sum (count maches), mean (proportion of matching)
