Why regex is not fuzzy matching
Recently, I cam across an interesting discussion on StackOverflow1 pertaining to approach to fuzzy matching tables in R. Good answer contributed by one of the most resilient and excellent contributors to whom I owe a lot of thanks for help suggested relying on regular expression, combining this with basic sting removal and transformations like toupper to deterministically match the tables. The solution solved the problem and was accepted. So what’s wrong… With this particular problem/solution pair, there is absolutely nothing wrong....
