R help - Jul 2003 - help for barchart(lattice)

I'd like to plot coefficients from glm result.
with barchart, coefficients are ordered by the names of factors and I'd like
to order them by values (or abs(values)).
to do that, I've ordered the vector of coefficients but it's plotting
the same thing.

I'm working R 1.6.2 on win98.
Thanks

is it possible to do that with standard graphical function?

You need to set up a factor for the grouping you want: the plot order is
along the levels of the grouping factor.  Take a look at the barchart
example for barley: neither year nor site are in alphabetical order.

An implicit call to factor will use alphabetical order, so use an explict
one.
