ThSQCA
ThSQCA: an R package for threshold-sweep QCA.
ThSQCA is an R package that reruns a QCA analysis across a range of thresholds, under identical settings, and records how the sufficiency solutions change. Truth table construction and minimization are delegated to the QCA package, so the computational core is the same as in a standard analysis.
