Updating Packages (was Re: [R] Reading of a large SAS Export dat

[Dr. Stephan Martin Rudolfer]

It was suggested to me that, although I've installed version 1.3.0 of 
R, the contained foreign package won't be the most recent.  Hence, 
it's worth using update.package().  However, when I did that, I got 
the following log file:

> options(CRAN="http://cran.us.r-project.org/")
> update.packages()
trying URL `http://cran.us.r-project.org//bin/windows/contrib/PACKAGES'
unable to connect to 'cran.us.r-project.org'.
Error in download.file(url = paste(contriburl, "PACKAGES", sep = "/"),  : 
        cannot open URL `http://cran.us.r-project.org//bin/windows/contrib/PACKAGES'
>
> options(CRAN="http://cran.r-project.org/")
> update.packages()
trying URL `http://cran.r-project.org//bin/windows/contrib/PACKAGES'
unable to connect to 'cran.r-project.org'.
Error in download.file(url = paste(contriburl, "PACKAGES", sep = "/"),  : 
        cannot open URL `http://cran.r-project.org//bin/windows/contrib/PACKAGES'
>

The first URL was inaccessible with Netscape. Yet when I directly 
accessed the second URL using Netscape, it worked perfectly, with the 
following result (severely edited to save space):

Package: bootstrap
Version: 1.0-7

Package: foreign
Priority: recommended
Version: 0.4-7

Could you please explain what I have to do to get download.file to 
work correctly?

Many thanks,
Stephan Rudolfer
