Hi,
I'd like to be able to generate a splom plot in R and then use my mouse to click on one of the sub-panels (panel.pairs, specifically) and have R return either the coordinates of that sub-panel, or even better, the names of the corresponding variables plotted in that sub-panel.

Here's an example to work with:

> library(lattice)
> splom(~iris[1:4], groups = Species, data = iris,
+       panel = panel.superpose,
+       key = list(title = "Three Varieties of Iris",
+                  columns = 3, 
+                  points = list(pch = super.sym$pch[1:3],
+                                col = super.sym$col[1:3]),
+                  text = list(c("Setosa", "Versicolor", "Virginica"))))

This is what I've been able to come up with so far, but I know it's not what I need. I'd like to be able to select an entire sub-panel

> trellis.focus()
> panel.link.splom() #click on a point in the plot, then hit 'esc'

[1]  80 111

> trellis.unfocus() #to end trellis.focus

Thanks for your help,
Eric
