Adrian Dusa's Miscellaneous
Description
Contains functions used across packages 'DDIwR', 'QCA' and 'venn'.
Interprets and translates, factorizes and negates 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 many others, a highly versatile recoding
routine and some more flexible alternatives to the base functions 'with()'
and 'within()'.
SOP simplification functions in this package use related minimization from
package 'QCA', which is recommended to be installed despite not being listed
in the Imports field, due to circular dependency issues.
