[R] Screeplot

[Jan Kleinn]

I'm trying to make a screeplot including the Cumulative Proportion of
the Variance, something that can easily be done in S-Plus with
'screeplot(pc.object,cumulative=T)'. How can I access the Proportion of
Variance in an princomp object and how could I get the Cumulative
Proportion of the Variance on the screeplot?

Many thanks in advance, Jan:-)
