Run the following in the Terminal: rm -rf /Library/Receipts/R-Framework* /Library/Receipts/R-GUI* In the rare case that you are non-admin user and the receipts were kept locally (I've never encountered this, though), you should also run rm -rf ~/Library/Receipts/R-Framework* ~/Library/Receipts/R-GUI* (Note: the meta-package may still show Upgrade although the R will be freshly installed because of the accompanying tools - see the custom install sheet for details) 2) How to remove all R from the system? Run the following in the Terminal: sudo rm -rf /Library/Frameworks/R.framework And delete R.app from wherever you installed it (usually the Application folder) If you installed additional tools (gcc 4.0.3) and you want to remove those, run also sudo rm -rf /usr/local/gcc4.0 If you want to remove a specific R version, look into /Library/ Frameworks/R.framework/Versions and delete the version you don't like. Adjust the "Current" softlink or use RSwitch to select another R version. > I cannot seem to find ALL the files to delete from my iMac in order > to avoid seeing "UPDATE" when I try to install a completely fresh > copy of R 2.4.0 Universal for Mac OS X. > Update is not a bad thing at all - it compares existing files, so it will do a fresh install anyway if you deleted previous version manually. Therefore in most cases you don't really care whether the Installer does an update or a fresh install - in terms of the installed product it makes no difference. The only difference is that Update will remove files in the old version that are no longer present in the new version - so update will affect the previous version (if present). This is why the ReadMe screen in the R package instructs you to delete the receipt (as shown above) if you want to keep your old version. Note that "upgrade" will still keep all additionally installed packages in the old version such that you can use the GUI to re- install all packages you had in the previous R version (see previous post on R-SIG-Mac).
