Compute Gower's distance (or similarity) coefficient between records. Compute the top-n matches between records. Core algorithms are executed in parallel on systems supporting OpenMP.


version 0.2.0

  • gower_dist and gower_topn gain weight argument for weighted matching (thanks to David Turner)
  • gower_dist and gower_topn gain ignore_case argument for automatic column matching.
  • gower_dist now returns numeric(0) invisibly when there are no columns to compare.
  • gower_topn now returns a list with empty matrices when there are no columns to compare.
  • gower_topn now warns when n>nrow(y) and sets n=nrow(y)
  • bugfix: comparing factors with characters would cause a crash (thanks to Max Kuhn)

version 0.1.2

  • fixed valgrind warning
  • registered native routines, as now recommended by CRAN

version 0.1.1

  • gower_dist now issues warning when nr of rows on input do not divide (recycling)
