R help - May 2009 - Overlay two quantreg coefficients plots

Dear R-mailing list,

I would like to overlay to two quantreg coefficients plots. I have
plot(summary(rq(ff~tipo,tau = 1:49/50,data=Spilldata)))
plot(summary(rq(ff~tipo,tau = 1:49/50,data=Spilldata1)))

Is there a possibility to display the two in the same graph?

Thank you so much!!!

Hi

I am unsure whether you want to plot the two summaries on the one
"panel"
or have 2 "panels" 1 for each summary

If it is the latter ? layout / ?par
