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,
