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`.
