grapes-equals-grapes: Detect pattern matches

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

Description

%=% is made for subsetting dataframes. Matching is case-insensitive and vectorized over string.

Usage

string %=% pattern

Arguments

string	A character vector.
pattern	A regular expression.

Details

This is almost identical to %like% but it ignores case by default. We could use base::grepl() or stringr::str_detect(), but we do a lot of subsetting, and %=% is as many as 30 characters shorter when ignoring case, while maintaining readability.

Value

A logical vector.

Examples

c('apple', 'banana', 'pear') %=% 'pp'

data(virginia)
virginia[OfficeTitle %=% 'house', .(OfficeTitle)]
