Hi,
I have R version 2.0.1 on my PowerBook G4 1.5Ghz, 512RAM, running OS X
10.3.9. I have noticed that the "official" R GUI runs considerably
slower than R in the terminal and also JGR. Whilst the differences in
speed are unimportant for simple parametric stats, it becomes a bit of
a pig when doing non-parametric stats e.g. neural nets, feature
selection algorithms.
In all my experiments I have set my CPU speed to "maximum" in system
preferences. I have also looked at the CPU usage for each
implementation: on average R in the terminal and JGR manage to get 98%
of CPU usage, compared to only around 75% for the R GUI.
I guess my questions are:
1) Why the difference in speed when its on the same machine?
2) Is there any way of tweaking R GUI to make it run faster, a la R in
the terminal?
Any help would be appreciated.
Best regards,
Sam.
