Is there an easy way to "thin" a lattice plot? I often create plots from
large data sets, and use the "pdf" command to save them to a file, but the
resulting files can be huge, because every point in the underlying dataset
is rendered in the plot, even though it isn't possible to see that much
detail.

For example:

require(Hmisc)
x <- rnorm(1e6)

pdf("test.pdf")
Ecdf(x)
dev.off()

The resulting pdf files is 31MB. Is there any easy way to get a smaller pdf
file without having to manually prune the dataset?

Thanks.
