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)

?reshape to wide format and matplot()?
Hmmm, that doesn't work if your measurements are at different times e.g: Oxboys2 <- transform(Oxboys, age = age + runif(234)) Hadley
