stringdist 0.9.4.2 released

stringdist 0.9.4.2 was accepted on CRAN at the end of last week.

This release just fixes a few bugs affecting the stringdistmatrix function, when called with a single argument.

From the NEWS file:

  • bugfix in stringdistmatrix(a): value of p, for jw-distance was ignored (thanks to Max Fritsche)
  • bugfix in stringdistmatrix(a): Would segfault on q-gram w/input > ~7k strings and q>1 (thanks to Connor McKay)
  • bugfix in jaccard distance: distance not always correct when passing multiple strings (thanks to Robert Carlson)

Actually the last bug has not bitten anyone since it was masked by the second one 🙂 (it was reported and fixed a long time ago but popped up again after fixing the second bug -- hat tip to Hadley for testthat!). The second fix also ensures that stringdist's memory allocator for q-gram storage is called fewer times which yields a speed gain in computation of q-gram based distances.
