R help - Jun 2009 - ggplot2 x axis question

Hi,
I have 45 models that I have named: 1, 2, 3, ... , 45 and I am trying to 
plot them in order of ascending BIC values. I am however unclear as to 
how I can get the models to line up on the x-axis by BIC and not by 
numeric order. For example, if model 5 has a lower BIC than 1, I want it 
to be the first point on the left hand side of the curve. This seems to 
work in plot:

plot(1:45, growthm.bic$delta, type="b", xaxt = "n",
xlab="Model",
ylab=expression(Delta[k]))   # where growthm.bic$delta is my BIC value
axis(1, at=1:45, labels=growthm.bic$Model) #where model is the name of 
the 45 models examined, i.e 1:45

Currently using qplot I have this which doesn't not work as it arranges 
the BIC values in order from 1:45.

qplot(model,delta,data=growthm.bic)

Thanks. Also please cc me as I am a digest subscriber.

Hi Chris,

Try this:

qplot(reorder(model, delta), delta, data = growthm.bic)
