Hmm, have you read getCRANmirrors? It works gracefully if the
connection is down, and has been tested quite a lot ....
It seems you got a corrupt read from the URL: that's not reproducible
and the place to deal with that is getCRANmirrors.
Please do use an informative subject line: it makes things *much*
easier to find in archives.

I was on leave and using a wifi internet connection in France and got connected,
launched R (2.10.1 on Windoze XPsp3) and tried to update my packages and got:
chooseCRANmirror()
Error in m[, 1L] : incorrect number of dimensions
It took me a bit to realise that the message was coming up because the wifi
connection had dropped. I know it's a small issue but is it possible to produce
a more informative error message. I can see a bodge of changing chooseCRANmirror
to:
function (graphics = getOption("menu.graphics"))
{
if (!interactive())
stop("cannot choose a CRAN mirror non-interactively")
m <- getCRANmirrors(all = FALSE, local.only = FALSE)
### bodge added here
if (ncol(m) != 8) stop("There was a problem with access to CRAN mirrors,
please check your internet connection")
### end of bodge
res <- menu(m[, 1L], graphics, "CRAN mirror")
if (res > 0L) {
URL <- m[res, "URL"]
repos <- getOption("repos")
repos["CRAN"] <- gsub("/$", "", URL[1L])
options(repos = repos)
}
invisible()
}
<environment: namespace:utils>
However, I'm sure you code gurus can do much better than that.
Many thanks for R: statistical wonderland, coding genius and a social movement
of which to be hugely proud!
