changeparam: Change simulation control parameter object

In mvattulainen/preprosim: Lightweight Data Quality Simulation for Classification

Description

Preprosim parameter objects contain eight contaminations: noise, lowvar, misval, irfeature, classswap, classimbalance, volumedecrease and outlier. Each contamination has three sub parameters: cols as columns the contamination is applied to, param as the parameter of the contaminations itself (i.e. intensity of contamination) and order as order in which the parameter is applied to the data.

Usage

changeparam(object, contamination, param, value)

Arguments

object	(preprosimparameter object)
contamination	(character) one of the following: noise, lowvar, misval, irfeature, classswap, classimbalance, volumedecrease, outlier
param	(character) one of the following: cols, param, order
value	(numeric) scalar (for order) or vector (for cols and param) of parameter values

Details

The order of contaminations (cols parameter) must be between 1 and 8, and no two contaminations can have the same order. The contamination parameter (param parameter) must start with 0 (e.g. param="param", value=c(0,0.3))

Value

preprosimparameter class object

Examples

pa <- newparam(iris)
pa <- changeparam(pa, "noise", "cols", value=1)
pa <- changeparam(pa, "noise", "param", value=c(0,0.1))
pa <- changeparam(pa, "noise", "order", value=1)
