Eval and go sends the commands to R and then jumps to the R buffer.  
Eval just sends the commands.

This is due to a glaring omission pointed out by Rich Heiberger: you  
need to set the running directory for Emacs when you use a desktop  
shortcut or the start menu. By default both the desktop shortcut and  
the start menu item runs everything in C:\progra~1\emacs-21.3\bin.  
Change it to whatever you think is appropriate. Properly your HOME  
directory if you are using that. (And you change this stuff by right- 
clicking on the shortcut/start menu item, choose properties and then  
edit the "run in" (or something similarly named) field.

I'm in the process of adding that to my setup guide.
