Hi,
is it intended that one cannot install packages in non-interactive mode,
without explicitly setting a CRAN mirror (see below)?
Couldn't a default mirror be used in that case?
Thank you.
You seem to be talking about installing from CRAN. The intention is
indeed that in non-interactive use you have to select the repositories
you want to use. See ?setRepositories and its links.
It is up to you to set a default mirror: we have little idea where you
live (and it may not be where your email address suggests). Geolocation
of mirrors had been mooted but not implemented (and in a corporate
setting is not 100% reliable). The whole point of mirrors is to spread
the load: without them there would be no CRAN as the main host would not
allow the traffic.
This would have been appropriate for R-help, if it would not have been
answered by doing the homework required by the posting guide (which also
requires no HTML ...).
Bests,
Renaud
