[R] regression with nestedness

Dear R-users,

I set up an experiment where I put up bluebird boxes across an urbanization gradient. I monitored these boxes and at some point I pulled a feather from a chick and a friend used spectral properties
(rtot, a continuous var) to index chick health. There is an effect of
sex that I would like to include but how would I set up a regression and look at the effect of urbanization (purban, a continuous var)) on feather properties of chicks within boxes.

So the model should look something like rtot = sex + purban +
(chick)clutch

Also, when I plot purban against rtot using the plot function I get boxplots but I would like to ignore the clutch and just plot each point.  I've tried type = "p" but this has no effect.

Thanks,

Jeff
