Hi, I am trying to draw some figures using the CO_PLOT method mentioned by Adi Raveh (1998). This method puts observations on a two-dimensional space using multiple dimension scale method, then add arrows to the panel based on the correlation between variables. Has anyone done the co-plot work in R before? It looks like biplot, but they are different. I am not sure whether vegan is the right package to do this, anyone has suggestions for this? Thank you so much! Best Hui -- Hui Xu Graduate Student School of Natural Resources and Environment University of Michigan, Ann Arbor Cell:517-899-6255 [[alternative HTML version deleted]]
