Which device are you working with?  Most of them allow the size to be 
selected in the initial call to open the window, e.g.

windows(2,2) for a very small window.  (The sizes are in inches, 
assuming your monitor reports the size of its pixels correctly.)

options("device") allows you to choose a new default; e.g.

options(device=function() windows(2,2))

to always get very small windows.

I don't know if any of the devices support programmatic changes from R 
code, but in Windows you could do most changes by sending Windows 
messages to the window or doing Windows API calls.  You can get the 
handle using getWindowsHandle(), and then you'll need to write C code to 
do the work.
