Dear R-users, I use R to run spatial stuff and it takes up a lot of ram. Runs can take hours or days. I am thinking of getting a new desktop. Can R take advantage of the dual-core system? I have a dual-core computer at work. But it seems that right now R is using only one processor. The new computers feature quad core with 3GB of RAM. Can R take advantage of the 4 chips? Or am I better off

Whether the two variables have the same units does not matter. Moreover, even if there were some way of converting cm to kg the correlation would still be the same because the correlation is invariant under unit conversion as it is invariant under multiplication of its arguments by a constant. As for your second question, the correlation estimator is a continuous function of each of the
