Whitespace around ggplot/Sweave generated plots

I am creating mapplots in using this code:

ggplot(fl, aes(long, lat, group = group)) +
    geom_polygon(aes(fill = density)) + guides(fill=FALSE) +
    geom_path(colour = "white", size = .1, alpha = .5) +
    scale_x_continuous(name = "", labels = NULL, breaks = NULL) +
    scale_y_continuous(name = "", labels = NULL, breaks = NULL) +
    coord_fixed()

Lat, long, and group are what you'd expect and this produces a map of Florida with counties different shades of blue. When I do this, it generates a PDF that is 6-in square. But the underlying plot is not square and for Maryland, it is really 5x3 or so. How can I force ggplot to create a PDF without excess whitespace surrounding the plot for better inclusion through Sweave?

set the width and height of the device / chunk to 5x3. – baptiste Jul 24 '13 at 01:08
Is there a way to determine the correct width/height programatically? – James Howard Jul 24 '13 at 01:11

Surely there's a better way of dealing with this, right? – James Howard Jul 24 '13 at 02:01

@JamesHoward There is, but it's a white wizard level secret. Sorry. – Simon O'Hanlon Jul 24 '13 at 11:32

I think this question just became an RPG. – James Howard Jul 24 '13 at 12:40
I think it should be closed as a duplicate – baptiste Jul 24 '13 at 12:53
Probably for the best. – James Howard Jul 24 '13 at 17:06
