[R] Help with graphics in gamm4 library

My problem is relatively straight forward, but I cannot seem to find a way to
make it work. 

I have a RCBD with repeated measurements over time. I have created a fit
using the gamm4 package. My model is: 

fit4a <- gamm4(Rate ~ s(Time,by=trt,bs="cr")+trt,data=qual.11.dat, 
              random=~(1|block),correlation=corARH1()) 

What I would like to create is plots with the X-axis being time, the Y-axis
being the fitted Rates for each individual treatment with the smoothed
curves overlayed on the plot. 

Every idea I have had to do this has resulted in some errors, and I have
reached my wits end. Can anyone steer me in the right direction?
