[R] how to suppress some tk dialogs

[jiho]

Dear List,

I noticed that, when executing R without X11 (e.g. on a remote machine  
without X forwarding), when R needs to display a Tk dialog (e.g. when  
presenting the list of mirrors for install.packages,or of available  
packages containing help on a given keyword) it replaces it by a  
simple numbered text list. I would love this behaviour to be the  
default, even when I have X11, since I find it quicker and less  
intrusive[1]. Is that possible?
man R, RSiteSearch and google were not helpful, it seems that  
everybody is trying to get Tk to work rather than trying to suppress  
it...

Thanks in advance.

[1] I am mainly using R in a simple terminal on OS X (X11 is usually  
not running, so each TK dialog has to start the whole X server) or via  
ssh to a remote machine (each Tk dialog has to start my local X server  
and needs to be sent through the network, twice as painful). This may  
give you the reason behind this seemingly strange question.

JiHO
