Overlaying lattice plots

There seems to be a problem here, probably of my own making... 

flqs <- FLQuants(list(observed=obs, fitted=fits))
xyplot(data~age,data=flqs)
Error in tmp[subset] : object is not subsettable
?

Morning chaps, I have a little question for your capable minds... Say 
I have an observed and predicted set of quants (in my case, length 
frequencies by year and age/length), is there a way to use lattice 
plots to plot the observed and predicted data together, panel by

panel?

Obrigado/gracias (thankyou in Galego is?...) Rich

Hi Richard,

If you want to plot both datasets on the same plot just make use of the
xyplot for FLQuants, something like

flqs <- FLQuants(list(pred=pred.quant, res=res.quant)) xyplot(data~age,
data=flqs)

now tune it the way you want and change the formula to fit your needs.

Regards

EJ
