install.packages problem on Windows: CRANextras timeout

Hello,

Thanks for the answer.
No, in the end there's no problem, just a warning.

As (I think) you notice below yourself, the problem is not with
the regular CRAN repos but with the  'CRANextra'  repos that
R users of Windows use sometimes.

We had heard offline of a potential timeout/downtime for a short
period at Oxford for that, so this may be the simple explanation.

On the other hand everything ends up working fine,
so all this is just a warning, right?

If I do the same thing I don't have to wait and get the same
warning as you (and when I then decide to use the older *binary*
for igraph that is installed fine).
