FW: [R] update.packages through proxy failing

[Duncan Mackay]

Hi all,
I have tried the helpful suggestion below from Andrew Ward, but I now get
the following error:-

> update.packages()
trying URL `http://cran.r-project.org/bin/windows/contrib/PACKAGES'
Error in download.file(url = paste(contriburl, "PACKAGES", sep = "/"),  :
        cannot open: HTTP status was `407 Proxy Authentication Required'
