Hello Jari, Thank you so much for your help. Yes, I have used percent data. I just know tried with the absolute counts and got, what I guess are right, values of AIC and BIC. Now coming back to the similar values, how can I discriminate in between the models with so similar AIC and BIC (and Dev

Hi Sheri, Thank you so much for the extra tools… some of them I already knew, some others don't. I appreciate your help!! S On Dec 17, 2013, at 12:52 PM, "Sheri O'Connor" wrote: > Hi Sol, > > I am assuming that your samples are stratigraphic? You might want to > check out the rioja package >

Martin, Thank you so much for your quick reply. I actually did the clustering trying both the R base package and pvclust. I am having trouble interpreting some results from the Ranked abundance distribution (see below). Thank you again, regards!! S On Dec 17, 2013, at 12:47 PM, Martin Weiser wr

Hi Sol, I am assuming that your samples are stratigraphic? You might want to check out the rioja package http://cran.r-project.org/web/packages/rioja/index.html for constrained hierarchical clustering (chclust function) by stratigraphic sequence. Another idea is biclustering using the method disc

Hello, I am trying to apply different statistics methods in a field that traditionally is not very keen to it… and in consequence I am trying to learn all that I can. To the point, I am studying a palynological succession from the Devonian. I have counts of palynomorphs (around 250) from a set
