R help - Nov 2012 - [lattice] print only legend

Is it possible to plot (and save) only the legend of a lattice plot? Of
course I could make the axes and axis labels transparent and use an empty
panel function, but additionally to being a very "dirty" solution,
there
would be still a lot of free space on the plot, while I would like to save
only the legend as a separate plot without any white space around it. Is
there a (nice) way to do this?

If you read the help page:

? xyplot

... it should not be too hard to find the section that names the grid function
that draws a key. Unsurprisingly, it is `draw.key`.
