Dear list members,

I am pleased to let you know that R met with QCA - Qualitative Comparative Analysis.
This package has a few functions that implement the Quine-McCluskey algorithm, adapted to social sciences by Charles Ragin (as describes in his book from 1987 "The Comparative Method").
Future versions of this package will have more functions to address the fuzzy-set minimization problems, as well.

Big thanks to the r-help list members, supportive as ever, especially to Gabor Grothendieck and Martin Maechler for excellent ideas in the key parts of the algorithm.
