[R] multiple lowess line in one plot

[Austin, Matt]

Try using the panel.plsmo function in Dr. Harrell's Hmisc package.

xyplot(AWGT ~ lipid, groups = var_name, panel=panel.plsmo)

Subject: [R] multiple lowess line in one plot


I'm using this code to plot a 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))
