Hi Henrik,

Could anybody behind a proxy check if the issue can be reproduced? My proxy is in fact provided by cntml, which acts as a local proxy that takes care of tricky authentication protocols with the actual university proxy, not natively supported by my system (Ubuntu). Anybody in this case?
I can replicate this on a WinXP system, where I normally have to use the --internet2 flag to get internet access through a proxy. ?download.file has a section on "Setting Proxies", which describes how to use environment variables to set proxy information. Setting http_proxy='http://my.proxy.com/' was enough for me to get R CMD check to run successfully with the --as-cran flag.
Thanks. Renaud

Hi, when I run R CMD check with flag --as-cran, the process hangs at stage: * checking CRAN incoming feasibility ...
Doesn't it time-out eventually? ?I'm not behind a proxy but when I've been running 'R CMD check' whenon very poor 3G connection, it had eventually timed out. /Henrik
I am pretty sure it is a proxy issue. I looked at the check code in the tools package and it seems that the issue is in the local function `.repository_db()` (defined in `tools:::.check_package_CRAN_incoming()`), which eventually calls `url()` with argument open="rb", that hangs probably because it does not use the proxy settings. I had a similar issue with `source()`, which apparently uses internal network functions (not as download.file), but is supposed to work behind a proxy (correct?). Does anybody else have this problem? I was wondering if there is a way around, as I would like to be able to use --as-cran for my checks. Thank you. Renaud -- Renaud Gaujoux Computational Biology - University of Cape Town South Africa
