<code>findSubsets</code>, <code>sortVector</code>, <code>sortMatrix</code>, <code>writePrimeimp</code> and
  <code>writeSolution</code> are internal functions of the QCA package which are not designed
  to be called directly by the user. All of them are used by the main <code>(e)qmcc</code>
  function(s), except <code>sortMatrix</code> which is used by <code>allExpressions</code>.
  The verification and error messages have been moved to the internal functions
  <code>verify.qmcc</code> and <code>verify.tt</code>.

QCA-internal

Performs the Quine-McCluskey algorithm for Qualitative Comparative Analysis, as described in Ragin, Charles C. 1987 "The Comparative Method. Moving beyond qualitative and quantitative strategies", Berkeley: University of California Press. In the classical approach it currently handles about 15 conditions and one outcome, but since version 0.4-5 the package has an enhanced, faster function that obtains the same exact solutions with a substantially lower memory consumption, and it handles even more causal conditions. The next versions of this algorithm will be oriented towards multi-value and fuzzy-set functions. Also, in the near future the current functions will deal with missing values in the data
