R help - Apr 2010 - how to set chart output size in rgl (surface3d)?

Hi R users,

Does anyone know how to change the size of 3d charts? I'm using surface3d in
rgl package, opening a new window each time to display the chart. I want it
so that the chart fills the whole window, because when I output it to png, I
don't want all the white space around the chart (right now, i'm getting
this
white "border" around the chart because the chart is smaller than the
window).

I know how to set the size of the window, but not the chart. When I make the
window smaller, the chart automatically resizes so it gets even smaller. Is
there a way to set the chart output size so it fills all (or most) of the
window?

Thanks for all your help!

Best,
Mandy

Open a window, resize it to the look you want (the right button 
resizes), then save the par3d("zoom") value into r3dDefaults$zoom. 
That
will be the default zoom for new windows you open using open3d.  (You 
may also want to save par3d("userMatrix") into r3dDefaults$userMatrix,
if you want to change the orientation of the default view.)

You can put the following at the beginning
library(rgl)
r3dDefaults$windowRect <- c(0,50, 700, 700)
