betterGrepl.any: Better grepl any

In debarros/dbTools: Functions From de Barros

Description

This function behaves similarly to betterGrepl, except that it returns only one logical value

Usage

betterGrepl.any(pattern, x, ignore.case = T, fixed = T)

Arguments

pattern	character string containing a regular expression (or character string for fixed = TRUE) to be matched in the given character vector. Coerced by as.character to a character string if possible. If a character vector of length 2 or more is supplied, the first element is used with a warning.
x	a character vector where matches are sought, or an object which can be coerced by as.character to a character vector. Long vectors are supported.
ignore.case	logical. if FALSE, the pattern matching is case sensitive and if TRUE, case is ignored during matching.
fixed	logical. If TRUE, pattern is a string to be matched as is. Overrides all conflicting arguments.

Value

Logical vector indicating whether any elements had matches

Examples

x = c("Alpha", "Beta", "Bet", NA_character_, "B")
betterGrepl.any(pattern = "a", x)
betterGrepl.any(pattern = NA, x)
betterGrepl.any(pattern = NA, x, ignore.case = F)
betterGrepl.any("Beta", x)
betterGrepl.any("beta", x)
betterGrepl.any("beta", x, ignore.case = F)
betterGrepl.any("B", x)
betterGrepl.any("X", x)
