Hello, I have just installed the newest version of R (2.4.1) for Windows XP. I can no longer install new packages. When trying to connect to a server (I have tried several) I get the following message:> chooseCRANmirror()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. Have other people had the same problem with this version, or is it unique to my computer? Can someone suggest a solution? Thanks. Bill Shipley [[alternative HTML version deleted]]
See if "2.19 The Internet download functions fail" in the R for Windows FAQ helps. Andy From: Bill Shipley> > Hello, > > > > I have just installed the newest version of R (2.4.1) for > Windows XP.
