all.expr

a vector of strings, the column names of the dataset

column.names

if not inside the qmcc function, print the result matrix without NAs

inside

There are $3^k-1$ possible expressions (where k is the number of conditions)
for a crisp-set procedure. This function creates a matrix by row-binding the truth tables
for all expressions.

misc

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. It currently handles about 8 conditions and one outcome. While theoretically it could handle more conditions, it requires a lot of computer resources and is memory hungry; future versions will have more functions to address this problem, as well as functions for fuzzy-set QCA. The package doesn't currently handle missing values in the data, therefore it is not yet possible to perform simplifying assumptions

all.expr: Create a matrix with all possible combinations of conditions
