The following works fine with the x11 device, though it
may well be that an initial plot is overwritten. With a pdf
or postscript device, I get two plots, the first of which
still has the red border from having the focus, while the
second is the plot that I want.
library(lattice); library(grid)
plt <- xyplot(uptake ~ conc, groups=Plant, data=CO2)
print(plt)
trellis.focus("panel", row=1, column=1)
arglist=trellis.panelArgs()
arglist$type <- "l"
do.call("panel.superpose", args=arglist)
trellis.unfocus()
Should I be able to use panel.superpose() in this way?
The new abilities provided by trellis.focus() etc add
greatly to the flexibility of what can be done with lattice
plots. The grid-lattice combination is a great piece of
software.
