There's also the lines() command which takes a col argument if you want to do multiple lines (I usually wind up wrapping it in a for loop though there might be something smarter)
ggplot2 is great, though the learning curve is a little rough: you can get good help here but if you go down that path, there's also a dedicated ggplot2 list that's worth checking out. Glad to have you as a new useR!
