Parse an object of class ProbDup to a data frame.

ParseProbDup converts an object of class ProbDup to a data frame for export.

ParseProbDup(pdup, max.count = 30, insert.blanks = TRUE)

An object of class ProbDup.


The maximum count of probable duplicate sets which are to be parsed to a data frame.


logical. If TRUE, inserts a row of NAs after each set.


A data frame of the long/narrow form of the probable duplicate sets data with the following core columns:

SET_NO The set number.
TYPE The type of probable duplicate set. 'F' for fuzzy, 'P' for phonetic and 'S' for semantic matching sets.
K The KWIC index or database of origin of the record. The method is specified within the square brackets in the column name.
PRIM_ID The primary ID of the accession record from which the set could be identified.
IDKW The 'matching' keywords along with the IDs.
COUNT The number of elements in a set.

For the retrieved columns(fields) the prefix K* indicates the KWIC index of origin.
