[R] Order in barchart

[Bliese, Paul D MAJ USAMH]

Sorry if this is a FAQ -- I checked the archives and help files, but was
stumped.

In the data T3 (provided below) the values are sorted from lowest to
highest.

If I use barchart in the trellis library, the bars are arranged by factor
order of the labels (1,10,11,12,etc.).

> barchart(T3,xlab="Mean Values",col="dark blue")

Would it be possible to have the bars arranged from highest to lowest in
terms of the values (2.65, 2.66, 2.73, etc.) as it is done in barplot?

>barplot(T3,xlab="Mean Values",col="dark blue",horiz=T,cex.names=.5)

I would like to use barchart instead of barplot because of some of the
additional features of the lattice library.

Thanks,

Paul
