It seems like this should be consistent with split(), since that's
what actually powers the behaviour.
Reading the description for split leads to this rather interesting example:
tapply(mtcars, 1:11, I)

The easiest way to do with this ggplot2 is to melt your data first:
dfm <- melt(df, id = "date", measure = c("theta","vega","delta"))

Hi Raj,
It's the same as the other plotting systems in R: you need to change
the order of the underlying factor levels. e.g.:
levels(diamonds$color) <- c("J", "D", "E", "I", "H", "F", "G")
If you're reordering then according to the value of another variable,
also see ?reorder

They are not slow. They are slower than vectorised equivalents, but
not slower than apply and friends.

Hi Michael,
You could use aes(y = 1000 * myyvar) and coord_trans(trans_y = "inverse")

You might want to check out the plyr package - it incorporates

Not really. What do you mean by crash? What do you mean by used together?

Philosophically, it's better to be explicit than implicit, and the

if + else and ifelse perform quite different tasks, and in general can
