[R] Best IDE for R

[Santosh Srinivas]

Dear R-Group,

I am looking for suggestions for the "best" IDE for R. Best is obviously
subjective but I need just the basic features that should function well (and
I looked through the threads already).
- Proper integration with R 2.11.1
- Good key shortcuts ... similar to the R Gui
- Manageability of Projects, etc.
- Neat formatting features

I tried Revolution R but it seems huge in size for something my basic needs
and keep throwing up configuration problems.
I tried Komodo. It works fine but having problems with "proper" integration
into R and unable to do debugging.

Any help?

Thanks,
S
