[R] xyplot with all columns of a data.frame on a single plot

[Rajarshi Guha]

Hi, I have a data.frame with columns named X, D1, D2, D3

I know I can get a single plot with 3 curves by doing

xyplot(D1 + D2 + D3 ~ X, data)

but in some cases I might have columns D1 ...  D10.

Is there a way to plot all 10 columns without having to specify each
individual term?

(By analogy with formulae in lm, I thought, xyplot(. ~ X, data) would
work, but it didn't)

Thanks,
