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
