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 **************************************** Jeffrey A.
