randfunc: Creates an R function with a random expression as its body

Description

Creates an R function with a random expression as its body

Usage

randfunc(funcset, inset, conset, maxdepth = 8, constprob = 0.2, exprfactory = randexprGrow, breedingFitness = function(individual) TRUE, breedingTries = 50)
randfuncRampedHalfAndHalf(funcset, inset, conset, maxdepth = 8, constprob = 0.2, breedingFitness = function(individual) TRUE, breedingTries = 50)

Arguments

funcset
The function set.
inset
The set of input variables.
conset
The set of constant factories.
maxdepth
The maximum expression tree depth.
exprfactory
The function to use for randomly creating the function's body.
constprob
The probability of generating a constant in a step of growth, if no subtree is generated. If neither a subtree nor a constant is generated, a randomly chosen input variable will be generated. Defaults to 0.2.
breedingFitness
A breeding function. See the documentation for geneticProgramming for details.
breedingTries
The number of breeding steps.

Value

A randomly generated R function.
