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’ (as ‘lib’ is unspecified) 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 Warning message: package ‘rpart’ is not available (for R version 3.1.1) Any help will be greatly appreciated!
