List assignment in a while loop and timing
...s on a quad core intel with
16GB ram running R-2.8
If I include the assignment A1 it takes ~85 seconds.
I have preassigned the list in line A0, so I'm guessing there is no resizing
going on, so why does the time increase so much?
Thank you for your time.
