RecordLinkage 0.4-0

• -The classes for linkage of big data sets have been redesigned. The mechanism of creating comparison patterns on the fly from a database is replaced by saving all comparison patterns in a ffdf object (disk-based data frame, see package ff). This approach limits the amount of comparison patterns with respect to available disk space (the database approach was designed to handle even more patterns, at least in theory), but is more efficient regarding execution speed. In addition, some methods that were only usable with the S3 class RecLinkData, can now be used with RLBigData objects, most notably getMinimalTrain(). For the structure of the redesigned classes, see the documention entries for classes "RLBigData", "RLBigDataDedup" and "RLBigDataLinkage".

RecordLinkage 0.3-5 (2011-09-12)

• -bug fixes: -getExpectedSize failed in rare cases

RecordLinkage 0.3-4 (2011-08-10)

• -added summary method for RLResult objects -bug fixes: -summary.RecLinkResult failed for object without known matching status

RecordLinkage 0.3-3 (2011-07-02)

• -added new classification method "bumping", see ?trainSupv -bug fixes:
• string comparators crashed for character(0) input (reported by Dominik Reusser)
• getPairs could fail when the result is emtpy -various performance improvements -renamed vignette "Fellegi-Sunter Deduplication" to "Weight-based deduplication" -package is now in a namespace

RecordLinkage 0.3-2 (2011-05-11)

• performance improvements in various functions
• bug fixes:
• epiClassify failed for datasets with only one column (reported by Richard Herron)
• getErrorMeasures returned wrong values in rare cases

RecordLinkage 0.3-1 (2011-03-24)

• fixed bug in emClassify that threw an error during classification with on-the-fly calculation of weights
• added checks in unit tests
• fixed bug in optimalThreshold which caused wrong results in some cases when ny was supplied

• fixed numerical problem that produced wrong thresholds in some cases for emClassify (with my / ny supplied)

RecordLinkage 0.3-0 (2011-03-15)

• A framework of S4 methods and classes tailored for processing large data sets has been added. See the vignette 'BigData' for details.
• The output format of getPairs (existing method for RecLinkData and RecLinkResult objects) has changed: Column "Weight" is now last instead of first. Also, for single.rows=FALSE, record pairs are speparated by a blank line.
