Integration with existing packages

Maciej Beręsewicz

1 Setup

library(blocking)
library(data.table)
library(reclin2)

2 Data

In the example we will use the same dataset as in the Blocking records for record linkage vignette.

data(census)
data(cis)
setDT(census)
setDT(cis)
census[, x:=1:.N]
cis[, y:=1:.N]

3 Integration with the reclin2 package

The package contains function pair_ann() which aims at integration with reclin2 package. This function works as follows.

pair_ann(x = census[1:1000], 
         y = cis[1:1000], 
         on = c("pername1", "pername2", "sex", "dob_day", "dob_mon", "dob_year", "enumcap", "enumpc"), 
         deduplication = FALSE) |>
  head()
.x .y block
204 1 1
204 176 1
204 375 1
204 391 1
204 405 1
204 424 1

Which provides you information on the total number of pairs. This can be further included in the pipeline of the reclin2 package (note that we use a different ANN this time).

pair_ann(x = census[1:1000], 
         y = cis[1:1000], 
         on = c("pername1", "pername2", "sex", "dob_day", "dob_mon", "dob_year", "enumcap", "enumpc"), 
         deduplication = FALSE,
         ann = "hnsw") |>
  compare_pairs(on = c("pername1", "pername2", "sex", "dob_day", "dob_mon", "dob_year", "enumcap", "enumpc"),
                comparators = list(cmp_jarowinkler())) |>
  score_simple("score",
               on = c("pername1", "pername2", "sex", "dob_day", "dob_mon", "dob_year", "enumcap", "enumpc")) |>
  select_threshold("threshold", score = "score", threshold = 6) |>
  link(selection = "threshold") |>
  head()

5 Usage with RecordLinkage package

Just use the block column in the argument blockfld in the compare.dedup() or compare.linkage() function. Please note that block column for the RecordLinkage package should be stored as a character not a numeric/integer vector.
