Possible uninstall problem on windows.
Note that Rversions.hta in http://batchfiles.googlecode.com is a Vista javascript script that will present you with a drop down list based on the R registry entries (and also allow you to change which version is current). Its a single file with no dependencies so just put it in your current directory (or anywhere in your path) and enter its name at the Windows command line to run it (or double click it from Windows Explorer). (There is an XP version in batchfiles 0.3-2.) On Sun, Oct 26, 2008 at 9:50 AM, Erich Neuwirth

I just uninstalled R 2.7.2 on Windows XP after having installed R 2.8.0 The uninstaller removed the String values HKEY_LOCAL_MACHINE\SOFTWARE\R-core\R\Current Version HKEY_LOCAL_MACHINE\SOFTWARE\R-core\R\InstallPath despite the fact that they pointed to R 2.8.0 The uninstaller did not remove the key HKEY_LOCAL_MACHINE\SOFTWARE\R-core\R\2.7.2 (and all the values in that key) I think the uninstaller should only remove the Current Version entry if it points to its own version. In a second attempt, the 2.7.2 uninstaller removed the key HKEY_LOCAL_MACHINE\SOFTWARE\R-core\R\2.7.2 (which is what it should do) but it still removed the HKEY_LOCAL_MACHINE\SOFTWARE\R-core\R\Current Version HKEY_LOCAL_MACHINE\SOFTWARE\R-core\R\InstallPath values. It should not have removed these keys. Sometimes this does not happen, and I have not found a consistent explanation when it happens and when not. Sometimes also running RSetReg.exe creates a second entry like HKEY_LOCAL_MACHINE\SOFTWARE\R-core\R\2.7.2 which has identical content with the first one. The registry really looks like having 2 identical entries. Is this something which I should file as a bug? -- Erich Neuwirth, University of Vienna Faculty of Computer Science Computer Supported Didactics Working Group Visit our SunSITE at http://sunsite.univie.ac.at Phone: +43-1-4277-39464 Fax: +43-1-4277-39459
