This issue causes another: evalPred with mostpopular does not work.
For example:
pop <- evalPred(e, "Popular")
Train set 1 / 2 created with 134 users, 28 items and 1290 ratings.
Error in (function (classes, fdef, mtable) :
unable to find an inherited method for function ‘predict’ for signature ‘"PPLclass"’
from rrecsys.
It seems that mostpopular method is only desined for recommendation, not prediction.
