...smoothed line. These two columns of data really represent 4 groups and I'd like to plot a separate line for each group but have them all in the same plot. The R-Docs for lowess do not seem to indicate some type of "GROUPS=var_name" option. What would be the syntax for this? plot(AWGT ~ lipid ) lines(lowess(lipid , AWGT, f=.8)) -- Dean Sonneborn, MS Programmer Analyst Department of Public Health Sciences University of California, Davis (530) 754-9516

I currently have 3 separate boxplots but would like to put them all in the graphic so they would have the same scale. Below are the three statements and as you can see the Y axis is weight: bwplot(AWGT~ male2 .... bwplot(AWGT ~ bin_pcb2 ..... bwplot(AWGT ~ bin_pcb2 | male2 ..... Does anyone have some sample code where they have done something like this? Thanks, Dean Sonneborn M.S.
