Fuzzy (case- and whitespace-insensitive) string equality

Source: R/sugar.R
fuzzy_match.Rd

The string counterpart to the numeric operator %~=% (see floating_point_comparisons). x %~% y is TRUE when x and y are equal ignoring case, leading/trailing whitespace, and runs of internal whitespace - handy for joining or matching messy, hand-entered data.

Usage

x %~% y

Arguments

x

a character vector

y

a character vector

Value

A logical vector, with NA where either side is NA.
