Select pairs for linkage using a threshold

1	select_threshold(pairs, threshold, weight, var = "select")

`pairs`	a `pairs` object, such as generated by `pair_blocking`
`threshold`	the threshold to apply. Pairs with a score above the threshold are selected.
`weight`	name of the score/weight variable of the pairs. When not given and `attr(pairs, "score")` is defined, that is used.
`var`	the name of the new variable to create in pairs. This will be a logical variable with a value of `TRUE` for the selected pairs.

Returns the pairs with the variable given by var added. This is a logical variable indicating which pairs are selected a matches.

data("linkexample1", "linkexample2")
pairs <- pair_blocking(linkexample1, linkexample2, "postcode")
pairs <- compare_pairs(pairs, c("lastname", "firstname", "address", "sex"))
pairs <- score_simsum(pairs)
# Select pairs with a simsum > 5 as matches
pairs <- select_threshold(pairs, 5)
