Thanks for your reply, Prof. Ripley.

Well, the reason for speculation was cos I couldn't find any details on 
that help page... thanks for letting me know that the reference explains 
this...

Ok, I will try these...

Oh, I most definitely should! :-) .. I guess I was hoping that such 
details would be included in the help page for the function or mentioned 
in some R introduction or tutorial or so on the Documentation page.. 
looks like that's not the case so I'll get a hold of the books above...

Thanks,
