getMatches function

getMatches

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'.

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.

Returns

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.

Examples

## Not run:

fl.out <- fastLink(dfA, dfB,
varnames = c("firstname", "lastname", "streetname", "birthyear"),
n.cores = 1)
ret <- getMatches(dfA, dfB, fl.out)
## End(Not run)
