R help - May 2007 - Accessing plots in Trellis graphics

Hi,

I used xyplot to create conditional scatterplots.  My layout is 5x3 
plots, but my data contains only 14 subgroups. So I would like to use 
the empty plot to display additional information about the data. How can 
I access the plot?

Thanks in advance

Here my call:

xyplot(yf~xf|id, data=data, pch=19, cex=0.5, col="black",
 panel=function(x,y, subscripts, ...) {
  ...
 },
 strip=function(..., factor.levels, fg, bg) strip.default(..., 
factor.levels=levels, style=4, strip.names=c(F,F), strip.levels=c(F,T), 
fg=bg), 
 layout=c(5,3),
)

I used similar empty space to place the legend, by specifying the placement
coordinates to the key argument of xyplot. 
This was rather long time ago, and I had to explicitly form the list, used
as the key argument for this function. Lattice has evolved since that, some
automation has appeared.

Try also using panel.identify, trellis.focus and other functions, listed on
the help page together with these two.

Another option is using page, as in this example from ?splom:

splom(~iris[1:3]|Species, data = iris,
      layout=c(2,2), pscales = 0,
      varnames = c("Sepal\nLength", "Sepal\nWidth",
"Petal\nLength"),
      page = function(...) {
          ltext(x = seq(.6, .8, len = 4),
                y = seq(.9, .6, len = 4),
                lab = c("Three", "Varieties",
"of", "Iris"),
                cex = 2)
      })
