generationFunctions function

Generation functions for biologically relevant function classes

These generation functions randomly generate canalyzing or nested canalyzing Boolean functions. These functions are usually not called directly, but are supplied to the functionGeneration parameter of generateRandomNKNetwork.

generateCanalyzing(input)
generateNestedCanalyzing(input)

Arguments

• input: A vector of input gene indices for the Boolean function

Returns

A binary vector corresponding to the result column of the truth table that represents the canalyzing/nested canalyzing function.
