handle large datasets in latticist? #39

Closed GoogleCodeExporter closed 8 years ago

Maybe look at handling very large datasets by
  - sampling
  - binning: levelplot / hexbin
  - summary stats like boxplot?

It is a bad idea to try to plot them, since lots of copies of the data end
up being made:
  - playState$trellis
  - grid display list
  - base display list
  - etc?

rather than 
qqmath(~ foo, f.value=ppoints(100))

subfoo <- quantile(foo, ppoints(100), na.rm=TRUE)
qqmath(~ subfoo)

it gets a bit more complicated if you want the sample to follow a distribution.

latticist has been split into a new package...
