Thanks, Uwe. I had tried that, with no success. It turned out that starting
R with the "--internet2" option (chosen when installing R) was not working for
me to allow access. I hadn't realised this because installing packages from
my national CRAN mirror did work, probably because the University that hosts
it is on my organisation's list of allowed sites. When I started R with my
explicit proxy server address, username and password, "install.packages
("XML")" did indeed work.
Does this imply something about the usefulness of the "--internet2" option?
