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()
