[R-SIG-Mac] Changing the colour of text output in the R.app Console?

[Thomas Richardson]

Hello,

Is there a command that allows the colour of text in the R.app console 
window to be changed?

I know that the colors can be changed manually via preferences, but I have 
been unable to find a way to do it via a command within the console. Does 
one exist?

I'd like to be able to write "print" functions that incorporate colour.

I know there is a package Xterm256 that will let you do this inside the 
Xterm version of R.

Many thanks for any suggestions.
