Thanks. Fig 4 in the link you provided is what I am looking for.

I still do not know how to implement my data1 and pca1 in the script you
provided as I think it is only a part of a full script.
pca1 <- princomp(data1[,1:4], score=TRUE, cor=TRUE) 

Am I right, how can I implement my data.frames?

Thanks again
