hi,
i am seeking for a solution to create a biplot that shows: 
a) data points instead of labels and that
b) shows two different groups (field: site with two factor levels: 
forest/corridor) in different colours
 
i tried to include "pch=19" to show points instead of labels in the syntax 
below but failed.
 
biplot(model, main="", iter=0.1,  cex=c(0.3,1.2), col=c(1,2))

i appreciate any hint.
 
best regards,
lukas
