Hi everybody, I am using vegan package. I have a matrix with 72 plant species, however most of them are irrelevant or not very important. When they are displayed together my plot is cluttered.So I want to constrain my biplot showing only species A B C D. How can I write the right code? I am trying the following code. mydata.pca<-rda(mydata) biplot(mydata.pca, scaling=-3) best, Jackson [[alternative HTML version deleted]]

Perhaps not sophisticated or elegant, but it will work. Rich
