getMatches: getMatches

In fastLink: Fast Probabilistic Record Linkage with Missing Data

getMatches

Description

Subset two data frames to the matches returned by fastLink() or matchesLink(). Can also return a single deduped data frame if dfA and dfB are identical and fl.out is of class 'fastLink.dedupe'.

Usage

getMatches(dfA, dfB, fl.out, threshold.match, combine.dfs)

Arguments

dfA	Dataset A - matched to Dataset B by fastLink().
dfB	Dataset B - matches to Dataset A by fastLink().
fl.out	Either the output from fastLink() or matchesLink().
threshold.match	A number between 0 and 1 indicating the lower bound that the user wants to declare a match. For instance, threshold.match = .85 will return all pairs with posterior probability greater than .85 as matches. Default is 0.85.
combine.dfs	Whether to combine the two data frames being merged into a single data frame. If FALSE, two data frames are returned in a list. Default is TRUE.

Value

getMatches() returns a list of two data frames:

dfA.match	A subset of dfA subsetted down to the successful matches.
dfB.match	A subset of dfB subsetted down to the successful matches.
