R Editor is not bad, but if I can choose, I would rather use a better editor that highlights syntax. I found that Notepad++ meets my requirements very well and more importantly it's free!
They also have a plugin/extension to use Notepadd++ with R. Please refer to the url below for mode details:

I'm now using NppToR which enables the communication between Notepad++ and R. All the tutorials as of how to install the package can be found from the URL above.
I also heard people talking about SciView too. Check it out.

Recently I found RStudio is super great, and I'm now using it most of the time.
This website collects lots of editors/IDE's for R.
