PARAFAC with PTAk in R?

This is not a programming question.  I am looking for someone with
experience using PTAk to perform PARAFAC (canonical decomposition CANDECOMP)
analysis on fluorescence EEMs in [R].  I want to transition into R for this
analysis since I already am using R for everything else. Most helpful would
be someone who has done this analysis with both Matlab-Nway and R-PTAk and
can thus explain what the NWay output analogs are in PTAk. 

Apologies if this question doesn't belong  here, but it seemed like the
least inappropriate place.

Thanks,
Thomas
