Convert a factor into integers using 0-based indexing
Description
Convert a factor (or an object that can be converted as such) into an vector
of integers indexed from 0 (instead of 1 as usual in R). This is what xgboost
expects as input for classification tasks.
Usage

Arguments
x
vector of class factor (or character).
Value
A vector of integers encoding factors, starting at 0.

defactor(factor(c("a", "b", "a")))
