This table shows the default values of nFeaturesInBag in terms of nFeaturesInBag/N for RGLM, RGLM.inter2 and RGLM.inter3. N is the total number of features of the training data. N is the effective number of features which equals the number of features N plus the number of interaction terms. Formulas are shown in terms of both N and the corresponding N. 1.0276 and 0.00276 are obtained by interpolating a straight line between (10,1) and (300, 0.2).
