mapFeat: Feature mapping function to polynomial feautures

In MarcoDVisser/rML: Machine Learning routines for R

Description

mapFeat maps the input variable X into quadratic feautures. for instance, if the input is a two dimensional array the function returns a new array with more features, comprising of X1, X2, X1.^2, X2.^2, X1*X2, X1*X2.^2

Usage

mapFeat(X, order = 2)

Arguments

X	an array to be mapped. Must be numeric!
order	the final polynomial order to map (defaults to 2), may take a long time if order is large. at this time also only accepts a value of two.
