createInteractions: Create all possible interactions (product, sum, difference)

In Thie1e/convenience: A small collection of diverse functions for more convenient working in R

Description

This function takes a data frame as input and returns all possible interaction terms, sums, differences or sums after taking the absolute value of every observation. Normalization before the calculations are carried out is possible. The function does only return the newly created terms, not the input data.

Usage

createInteractions(x, type = NULL, normalize = T, excludeFactors = T)

Arguments

x	A data frame with column names
type	"*" for all possible products, "-" for all possible differences, "+" for all possible sums and "absSum" for all possible sums after taking the absolute value of the observations.
normalize	If TRUE, normalize all columns before carrying out any calculations. TRUE by default.
excludeFactors	If TRUE, excludes all factor variables from the calculations. Otherwise, a high number of variables may be created if the data includes a lot of levels. TRUE by default.
