Nuber of rows in predict.rFerns doesn't match rows of newdata

Seems like you haven't passed the testing set to the predict function, this way it just drops the OOB predictions -- such use case in covered by unit tests, so bug is unlikely.

mRMRe::mrmr vs praznik::mrmr

AFAICT, mRMRe calculates mutual information by estimating from correlation between features, using the formula `I(x,y)=−.5 log (1−cor(x,y)^2)` (this is why it expects numerical input), while praznik from a direct formula `I(x,y)=p_xy log (p_xy/p_x/p_y)` for categorical variables (and this is why it expects factors)... So these are basically different algorithms, or let's say, versions of mRMR using different interface to the data.
