Hi, I have a couple questions about fitting environmental (land use
factors, plant species presence-absence, and soil variables) constraints to
my CCA biplot. 1. After successfully plotting species and site scores in my
CCA, I have been trying to insert the biplot arrows of the environmental
constraints in my data set using the text() function. When I do that, the
plot changes completely. Is there some code or a sample script you could
let me know about? 2. I would like to include only the environment
constraints that are significant at conf=0.95, but am not sure that I can
do that in a CCA biplot. I was hoping that this way I could make my plot
less crowded.
Thanks!
