R help - Mar 2010 - Plot help

Is there an easy way to do two things:

I have a dataframe with headers and 18 columns

I want to plot all the columns on same y axis plot(df) does this.

BUT

1. There is no legend, the legend function seems pedantic - surely there
must be an easy way to just pick up my headers?

2. How do I vary the colours. By default they repeat quite frequently and I
have lots of red lines etc.

No. If df is data frame you shall get pairs plot.
