R help - Apr 2011 - Line plots in base graphics

Am I missing something obvious on how to draw multi-line plots in base graphics?

In ggplot2, I can do:

data(Oxboys, package = "nlme")
library(ggplot2)

qplot(age, height, data = Oxboys, geom = "line", group = Subject)

But in base graphics, the best I can come up with is this:

with(Oxboys, plot(age, height, type = "n"))
lapply(split(Oxboys[c("age", "height")], Oxboys$Subject),
lines)

Am I missing something obvious?

Thanks!

 reshape to wide format and matplot()?

It appears you've been infected with what I like to call "the Dijkstra
syndrome" [*], quoting

"The tools we use have a profound (and devious!) influence on our
thinking habits, and, therefore, on our thinking abilities."

You can probably blame ggplot2 here, messing with our minds and
spoiling us. I can't seem able to think like spreadsheets anymore
either, because of R.

Thanks though,
