[R] uninstalled and reinstalled R, now cannot install packages
Hello, I have a student (running Windows 8) who ran into a problem installing the RcmdrPlugin.IPSUR package and, despite instructions to the contrary, uninstalled R and reinstalled. He uninstalled it using the Windows 8 utility. Now he cannot install any packages. Here are the error messages he gets when he gets when he trys to use the menu to install a package:> utils:::menuInstallPkgs()--- Please select a CRAN mirror for use in this session --- Warning: unable to access index for repository http://cran.mirrors.hoobly.com/bin/windows/contrib/3.1 Warning: unable to access index for repository http://www.stats.ox.ac.uk/pub/RWin/bin/windows/contrib/3.1 Error in install.packages(NULL, .libPaths()[1L], dependencies = NA, type type) : no packages were specified In addition: Warning message: In open.connection(con, "r") : unable to connect to 'cran.r-project.org' on port 80. Here are the messages he gets when using the install.packages command (it doesn't matter what package he tries to install):> install.packages("rpart")Installing package into ?C:/Users/michael.bottai/Documents/R/win-library/3.1?

[R] uninstalled and reinstalled R, now cannot install packages
Inability to access a repository index is very often an indication of a failed
internet connection from R. In Windows that is often a result of incorrect proxy
settings or other internet connection settings. The R Windows FAQ, 2.19
("The Internet download functions fail") may have the answer...
As a quick diagnostic, try running
setInternet2(use = TRUE)
as the _first_ thing after starting R. This will effectively cause R to use the
same settings as Internet Explorer. If that works, add the flag --internet2 to
the command line in the R shortcut.
If that fixes the problem, edit the Windows shortcut to include --internet2 in
the command lione.
If it fails, see Windows FAQ 2.19 (b).
have a look at either edit your local R config file to use internet2 instead of
the default, or reinstall R, setting the Internet2 option during the
installation process.

Hi, If your PC connects Internet via proxy server, you have to run Rgui.exe with option "--Internet2" (i.e. Rgui.exe --Internet2). If my suggestion doesn't make sense, please ignore. rgds. --- Ryota Kawauchi 2014/10/01 13:39?Sarah Hardy <sarah.hardy at maine.edu> ??????:> Hello, > > I have a student (running Windows 8) who ran into a problem installing the > RcmdrPlugin.IPSUR package and, despite instructions to the contrary, > uninstalled R and reinstalled.
