[R] Multi-line plots - max Y?

Hi all, OK, I'm struggling a bit with getting good basic plots so I put together this little example. It works - sort of - but it seems a bit hokey to me. Can someone suggest how a pro would do it? The goal is to take data from 4 columns of a data.frame (data read in by read.csv) and
