No. The R icon in the Applications folder is the GUI front-end. The R  
versions and supporting modules are stored in the Frameworks folder.  
If you are going to a new version within a major release, i.e. R  
2.10.0x to 2.10.1 then you may not need to trash the GUI. And major  
version upgrades get new folders anyway and the /Current/ links get  
updated. Then you would need a new GUI, but the old GUI would get  
overwritten anyway with a new release when you dragged the R.app and  
R64.app from the disk image to the Applications folder, unless you  
rename them first.
