hat is important, results are in the same format as input data
(class <code>big</code>), so you can use <code>forward</code> again or
in combination with other functions (with different criteria if you
like). The pipe (<code>%&gt;%</code>) operator will be helpful. For
every step the actual number of variables in a model, mean squared error
(<em>MSE</em>) or accuracy (<em>ACC</em>; if you use the logistic
regression) and a value of the chosen criterion (<em>crit</em>) are
given.</p>
