It is nearly the same example I wrote about in http://www.mail-archive.com/r-help@stat.math.ethz.ch/msg54238.html. I'll print it out again:
In the first column I have numbers from 0 to 23 (hours of a day), the second column contains the name of a weekday (Day as factor) and the third column contains the number I am interested in. So as an example, the first five rows look like that: Hour Day Freq 1 0 Mo 23 2 1 Mo 20 3 2 Mo 14 4 3 Mo 27 5 4 Mo 26 To read: On Monday between 0 and 1 o'clock 23 things happened. Now I add a new parameter, so that the data looks somehow like that: Hour Day Freq Freq2 1 0 Mo 23 874 2 1 Mo 20 476 3 2 Mo 14 201 4 3 Mo 27 912 5 4 Mo 26 172 Now I'd like to have a plot for every weekday containing the two frequencies as a line during the hours. Is this possible with two y-axes? Thanks for your help, Antje -----Ursprüngliche Nachricht----- Von: Deepayan Sarkar [mailto:[EMAIL PROTECTED] Gesendet: Montag, 9.

The answer depends on the details of what you are doing, so please provide us with a reproducible example.
