So Mike, let me ask you a question. If R runs out of RAM, does it
begin to use virtual RAM, and hence begin to swap from the hard drive?
If so, I could see how a faster hard drive would speed R up when you
don't have enough RAM...
Yes. Virtual memory management is done
I am hoping something has changed since I last asked about this.
Is there any good source of documentation, including examples, of using
tcl/tk as a gui for R applications?
