Usage

## S3 method for class 'RLBigDataDedup':
summary(object, ...)
  ## S3 method for class 'RLBigDataLinkage':
summary(object, ...)
  ## S3 method for class 'summaryRLBigDataDedup':
print(x, ...)
  ## S3 method for class 'summaryRLBigDataLinkage':
print(x, ...)

Arguments

object

The object for which to show a summary.

Return value of the summary function.

...

Additional arguments from the generic function are ignored.

Value

For summary, a list with components
nDataOnly for the "RLBigDataDedup" method: Number of records in the dataset.
nData1Only for the "RLBigDataLinkage" method: Number of records in dataset 1.
nData2Only for the "RLBigDataLinkage" method: Number of records in dataset 2.
attributesColumn names of dataset(s).
blockFldBlocking definition as a list of character vectors, representing column names.
nPairsNumber of record pairs
nMatchesNumber of matches in the set of record pairs.
nNonMatchesNumber of non-matches in the set of record pairs.
nUnkonwnNumber of record pairs with unknown matching status.

Blocking fields are displayed in a style like [attr1], [attr2, attr3], where attr1 etc. are column names and attributes within brackets represent one blocking iteration. See compare.dedup or RLBigDataDedup for an explanation of blocking criteria.

Examples

Run this code

data(RLdata500)
  rpairs <- RLBigDataDedup(RLdata500, identity = identity.RLdata500,
     blockfld=list(1,3,5:7))
  rpairs <- epiWeights(rpairs)
  summary(rpairs)
