%description
The aim is to take in data.frame inputs and utilises methods, such as
recursive feature engineering, to enable the features to be removed. What
this does differently from the other packages, is that it gives you the
choice to remove the variables manually, or it automated this process.
Feature selection is a concept in machine learning, and statistical
pipelines, whereby unimportant, or less predictive variables are
eliminated from the analysis, see Boughaci (2018)
<doi:10.1007/s40595-018-0107-y>.
