Good Morning,

I have 3 sets of data, all with the same horizontal axis but with varying
vertical input.  I want to plot all 3 sets on one x-y plot.  I can get 3
linear regression plots and 3 polynomial regression plots on the same chart
but I have not been able to get more than one set of input data on the same
chart.  Can you help me?

Thank you for all that you do to provide R to the public.
