grapes-grapes: Remove pattern matches

In MEDSL/medslcleaner: A MEDSL Package for Cleaning Election Returns

Arguments

string	A character vector.
pattern	A regular expression.

Details

The equivalent alternatives are str_remove_all(x, regex(pattern, ignore_case = TRUE)) (which this function wraps) or gsub('pattern', '', x, ignore.case = TRUE).

Value

The vector string without any substrings matching pattern.

Functions

• %r%: Alias for removing a pattern match
