To reproduce a reasonable facsimile of the 'bringToTop()' function  
that is part of the auto-loaded grDevices package on other platforms,  
define the following function in your RProfile.site file (to run at  
start-up)

bringToTop<-function(which=dev.cur()) {system("osascript ~/Library/ 
Scripts/RScripts/RBringToTop.scpt")}

The path to the Applescript that is invoked via osascript may vary  
depending on where you store the following Applescript. Note that I  
don't use X11 display, so I am only applying 'bringToTop' to quartz  
graphic windows and R Console. The extension to X11cairo devices   
(duplicating the second tell block with minor modifications to target  
X11) should be obvious. Also, I prefer to select the graphic window  
from a list. It is also possible to pass an argument to a script by  
bracketing it with  "on run argv ... end run" , where argv contains  
the passed parameter as a string, for example the output from  
dev.cur(), or dev.list(). As is, the script can be run directly from  
the Script menu or terminal without defining bringToTop() in R.

I  am enormously grateful for the work and effort that has been put  
into the Mac port of R and R.app GUI.  However, there are a couple of  
functions I miss from other versions, and I was wondering if there is  
an easy way to add them.


2) bringToTop() would bring the active graphics window to the  
foreground, but seems to be missing from the Mac port. I've tried  
various ways of designating the active window etc, but none bring it  
to the foreground.
