[R] Mac OS X R uninstallation question

[Alastair]

Hi,

I've been using R for a number of years and have always installed the newest
version when released. However I've just noticed that old versions of R are
taking up quite a lot of disk space.

lap-alastair:/ alastair$ du -h -d 1
/Library/Frameworks/R.framework/Versions/
266M	/Library/Frameworks/R.framework/Versions/2.10
204M	/Library/Frameworks/R.framework/Versions/2.11
459M	/Library/Frameworks/R.framework/Versions/2.12
511M	/Library/Frameworks/R.framework/Versions/2.13
478M	/Library/Frameworks/R.framework/Versions/2.14
217M	/Library/Frameworks/R.framework/Versions/2.15
32K	        /Library/Frameworks/R.framework/Versions/2.5
5.5M	/Library/Frameworks/R.framework/Versions/2.6
84M	/Library/Frameworks/R.framework/Versions/2.8
2.2G	/Library/Frameworks/R.framework/Versions/

Do I need to keep any of the versions before the current (2.15). If I delete
all the previous versions will that have any impact on the current
installation, or is each version entirely self-contained? 

Thanks.
