matchStrings: Match strings in A with strings in B

In vapniks/mergeutils: Functions to aid merging and checking disparate data

Description

Match strings in A with strings in B

Usage

matchStrings(A, B, onto = TRUE)

Arguments

A	A character vector
B	A character vector
onto	If TRUE (default) then ensure all strings in B are matched by at least one string in A if possible.

Details

This function tries to match the strings in 'A' to the closest ones in 'B'. By default it tries to ensure that every element of 'B' is matched by at least one element of 'A'. So if 'A' and 'B' have the same length it calculates an exact pairwise matching between 'A' & 'B'. If length(A) < length(B) then some elements of 'B' will not be matched. If length(A) > length(B) then some elements of 'B' will be matched more than once. Alternatively, if the 'onto' parameter is set to FALSE then each element of 'A' will be matched with the most similar element of 'B' regardless of whether or not that element is matched by another element of 'A'.

Value

A vector whose i'th entry indicates the element of B that matches the i'th element of A
