Dear R users, I need to know whether the factor graphics with principal component analysis are implemented in R. I mean the graphs where the variables are represented in a correlation circle, as described in more detail in this document: http://www.unesco.org/webworld/idams/advguide/Chapt6_4_3.htm It is not a pain to program it myself, nevertheless it would be a waste of time if it is already implemented in R. Regards, Martin

Take a look at the FactoMineR and vegan packages. They may contain what you are looking for. Greg
