Hello, Rusers:
I have a question to ask for your help. The data has three columns: a, b and
c.
We need to draw an overlaid plot of curves of "a" versus "b" for different
c. That is, draw many curves in one plot and each curve uses a different
symbol.
Does R have such functions? I have searched for a while. But seems not. I am
new to R. Your help is highly appreciated.
Many thanks. Looking forward to your response,
Sun
