Description Usage Arguments Value Examples

Search for pattern matches, where trying to match to NA comes back as FALSE

1	betterGrep(pattern, x, ignore.case = T, fixed = T)

`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.

Numeric vector holding the indices of elements of x that had matches

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