Arguments

patterns	a character vector of regex or fixed patterns.
x	a string to search for the match.
fixed	a logical, indicating whether patterns are fixed strings.

Value

Logical vector of length as patterns with true if pattern was found.

Examples

"The quick brown fox jumps over the lazy dog", FALSE)
igrepl(c("today","brown fox", "jumps over", "vigorous"),
"The quick brown fox jumps over the lazy dog", TRUE)
