Removed set.seed(1) from ppgam(), which clearly shouldn't have been left there! (Thanks to Patrik Bohlinger for spotting this.)
Added argument weight.non.numeric to function ppgam(), which allows weights to be calculated for non-numeric variables according to their frequency of occurrence.
Added functionality for S3 methods, coef(), logLik(), simulate() and fitted().
ppgam() has had a couple of lines changed to account for changes in evgam:::.joinSmooth()
