Hi All,
I installed R 2.5.1 recently on a PC (Windows XP Professional 2001) and tried to install some R packages. It took several minutes and gave me the following message. > utils:::menuInstallPkgs() --- Please select a CRAN mirror for use in this session --- Error in open.connection(file, "r") : unable to open connection In addition: Warning message: unable to connect to 'cran.r-project.org' on port 80. in: open.connection(file, "r") Error in contrib.url(repos, type) : trying to use CRAN without setting a mirror I am just wondering whether this problem is caused by restrictions on internet imposed by my work unit or caused by something else. If the later, how to solve it? Thanks in advance.
