Dear R,
I have a question concerning quantile regression models.

I am using the quantile regression model to test the relationship between 
abalone and the percentage cover of algae etc at different sites and depths.

An example is
fit<-rq(abalone~%coversessileinvertebrates+factor(Depth)+factor(Site),tau=0.7)

In this model depth is fixed and site is random. My question is, is it
possible specify the fixed and random effects in this model. If so could
someone please give me an example of how to write the code.

I can;t seem to find any information in the R help.
Thanks in advance
 Beth Strain
