I've been using the pcaMethods to develop a scores matrix ======================================= data(iris) pcIr <- pca(iris[,1:4], method="nipals", nPcs=3, cv="q2")
test <- scores(pcIr) ======================================== What I'm looking to do is to use lattice's barchart to plot the scores something like below, but expanded to all the scores columns. Can someone give me a clue? I've thought about restructuring the data, but I'm not sure as to the best method to do this. (This is an example only....) =========================== barchart(test[,1],origin=0) =========================== Thank you kindly, -------------------------------------------------------------- Shawn Way, PE MECO, Inc.
