can Mac run multiple R tasks
The Max (OS X) is a great Unix box. Some things are best
done on RGui, and some (more, the way I see it) on the Unix side.
There are less than 10 ESS commands one really wants, maybe
ESC-x R (start an R process)
(if required do it again &
again, but Xple
processes can breed confusion!)
ESC-x ess-rdired (get a list of objects in the workspace, mark
d or D for delete, u to undo,
and x to execute)
(This is a truly great feature.)
C-c C-d (dump obj or function into an edit buffer)
C-c C-l (load from edit buffer back into R)
C-c C-n (feed lines one at a time from a .R buffer into R)
C-x 4f (emacs command to load file into a split of the current
window)
C-x 5f (emacs command to load file into a new window)
Plus, there are the emacs commands that search back through the
buffer.
There are a few others that I use infrequently. Also, some of these
can be done from the menu.
Mac users should consider using emacs and ESS, sticking, until greater
adventure calls, to just a small subset of its features.

Just to expand a little on David's answer...
In the last few days I have been running four or five simulations
simultaneously on a Mac Pro by starting them from the command line.
The code for the simulation is in a file foo.R and it is run from
Terminal with
$ R CMD BATCH foo.R &
Issuing a similar command multiple times results in multiple parallel
instances of R to run.
For nice R graphics on OS X, use the quartz device with the CarbonEL
package. I have in my ~/.Rprofile file:
library("graphics")
library("CarbonEL")
options(repos = "http://cran.ca.r-project.org", menu.graphics =
FALSE, device = "quartz")
As an aside, if you frequently want to run multiple instances of R
(e.g. to work on different projects), I would recommend using R from
within Emacs with ESS; see
http://cran.r-project.org/doc/FAQ/R-FAQ.html#R-and-Emacs
On OS X, I use Aquamacs (http://aquamacs.org) which comes bundled with
ESS. No setup necessary!
[I know, this is more of a Unix than Mac-like approach...]
Hope this helps!

Don't forget you can run R from Terminal. So there you can have any number of Terminal windows open, each with its own R. You can even open a quartz device (although non-interactive). You can also run it under X-windows (from xterm for example) and there you have an x11 device.

Hi, I am a new MacPro user. So far, I am very happy with the performance of MacPro. However, I cannot not figure out if I can open multiple R Console to run multiple R tasks in my MacPro. Every time I click R icon and want to start a new task, the old R task will always pop-up. Let me know if you have answers. Thanks. Ling
