Hi! Thanks for providing great help in R-related statistics. Now, however I'm stuck. I'm not a statistics person but I was recommended to use R to perform a nmds plot and PerMANOVA of my dataset. Sample(treatment) in the columns and species (OTU) in the rows. I have 4 treatments (Ambient Temperature, Ambient temperature+Low pH, High temperature, High temperature+low pH), and I have 16

...clusters, by cutting the tree using cutree with k=48. I would now like to estimate the distance between each pair of the 48 resulting clusters. I have read the documentation, but I cannot find a solution. Any clue on how I can do that? This is a snippet of the code: distPredTurn<-as.dist(dissimilarityMatrix) hctr<-hclust(distPredTurn,"ward") cutree(hctr,k=48) Regards -- Corrado Topi Global Climate Change & Biodiversity Indicators Area 18,Department of Biology University of York, York, YO10 5YW, UK Phone: + 44 (0) 1904 328645, E-mail: ct529 at york.ac.uk
