Adrian Dusa's Miscellaneous
Description
Contains functions used across packages 'QCA', 'DDIwR', and 'venn'.
Interprets and translates DNF - Disjunctive Normal Form and SOP - Sum of
Products expressions, for both binary and multi-value crisp sets, and extracts
information (set names, set values) from those expressions. Other functions
perform various other checks if possibly numeric (even if all numbers reside
in a character vector) and coerce to numeric, or check if the numbers are
whole. It also offers, among others, a highly flexible recoding function.
