Using ' fitted' for plots-lme

["Gupta, Pankaj*" <GuptaP@cder.fda.gov>]

Dear users,

I wish to generate a plot of the population fitted values vs.observed values for a linear mixed effects model. The following gives the individual fitted values vs. observed values:

plot(lme.fitfile,response variable~fitted(.))

 Is there a similar way to get the population fitted vs .observed plot?

I'd appreciate any help in this regard.

Thanks

Pankaj
