Well, perhaps the site (which is not www.r-project.org) was unavailable or inaccessible when you tried.
Happily it works again, now, but I don't know why...
This morning, I browsed (with IE or Mozilla) http://cran.r-project.org/bin/windows/contrib/1.8/PACKAGES when R was not able to find it. I tried several times (and was able to download contributed packages with my browser) and the same problem occurred each time.
Internet caches can make sites appear
available when they are not, and the download processes do try to avoid
cached copies.
You seem to have --internet2 as your command-line flag (from the error message), so you do need to check you can access the exact URL *from Internet Explorer*. (BTW, that is a crucial piece of information that you did not supply.) If you use Mozilla, why do you have --internet2?
Because I also use this machine in my office. Our network administrator wants us to use IE and he configured it to work with the local network and the proxy server. When I am home (where I use a dial-up modem), I prefer to use Mozilla.
Note too that if R has not been changed, this is not a problem with R but with your own computer, and we are not going to be able to debug something you changed on your own machine, are we?
Sure, and I did not mean that ! I was just puzzled and worried by this unusual behaviour.
Thanks for your reply.
Best regards,
Renaud

Dear all,
I am working with MS Windows XP Pro (latest update) and a pre-compiled version of R:

I meet a strange problem with install.packages and update.packages (called from the menu), that did not occur until today:

I still can access http://www.r-project.org/ and any of its section (including download) with my browser:
Mozilla 1.6 Mozilla/5.0 (Windows; U; Windows NT 5.1; fr-FR; rv:1.6) Gecko/20040113
The only thing I recently changed on my computer was to update Mozilla (from 1.5 to 1.6).
Any hint will be highly appreciated.
Best regards,
Renaud
