> I have a couple of questions:
> * would it be possible to add more information on the history, for 
> example the number of the command and a timestamp. With the number of 
> command, one could do some stuff like in a terminal to recall 
> a specific 
> command :
> $ !45
> and with the timestamp, one could imagine to ask for commands 
> that were 
> typed in a given interval of time. For example :
> R> history(before="Thu Apr 13 8:54:14 2006")
> 
> * My other question is about the prompt, is it possible to make it 
> dynamic, ie to mimic the PS1 variable in bash. R would use a 
> prompt that 
> would tell (for example) the current time, and the number of 
> the command 
> to come
> [445-10:58:54] R>
