[R] Deleting the White Space in an R graph

[Greg Snow]

The squishplot function in the TeachingDemos package will move the axes
and other annotation closer to the plot so there is less whitespace
within the plot region (there will still be whitespace in the margin
areas beyond the axes and labels).  Is this what you want?

To completely eliminate all the whitespace you will need to set up your
graphics device to the correct size (the computations done in squishplot
may help) and set the margins to only include enough room for what you
intend to put there.  One possible approach for this is:

1. plot using squishplot
2. use the locator function and click on the edges of what you want in
the graph
3. use cnvrt.coords (also in TeachingDemos) to convert the results from
locator to device coordinates
4. start up your graphics device with the height and width proportional
to the result from 3
5. use par(mar=c(...  And put in just enough room for the annotations
you will use.
6. create your plot 
7. if it does not match what you want, then adjust accordingly and
repeat.

Hope this helps,
