During installation of R, at least 2 folders are involved.
/Applications/R.appfolder: contains GUI
/Library/Frameworks/R.frameworkfolder: contains R framework
(unkown) /usr/bin: contains some links
When uninstalling, R under Mac OS X will delete all of them.
Uninstallation steps as follows:
- open terminal in Mac OS X
rm -rf /Library/Frameworks/R.framework /Applications/R.app \ /usr/bin/R /usr/bin/Rscript
