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
