R help - Feb 2003 - Help needed regarding acf

Hi,

 When I plot the auto co-relation function (acf), 2 blue lines appear near the
base. Can anyone tell me what they mean?

Also can anyone tell me how to print the graphs that are generated. There is a
print option but when I click on it, it doesn''t seem to do anything. Is
copying the graph as a bitmap file in paint the only way out?

 Thanks for any help.

Regards,

 Shalini

The lines are representing the confidence interval. See ?plot.acf for
details.

No, there are several ways! Please read the manuals and ?Devices !
