Question about proxy setting of R
As far as I can see, the 'internal' method doesn't work for https mirrors (on my system, anyway). However, the http mirrors still exist (try " http://cloud.r-project.org/" for example) so why not just use one of those? Cheers, Carina

I assume the proxy server is only available for "http", not "https".
What should I do ?

Try this option:
options(download.file.method = "internal")

Hello,
I use R 3.0.2 on Win 7 through proxy server using ".Rprofile" in home
directory that includes "Sys.setenv(http_proxy=proxy_ server:port)".
There has been no problem to access the internet for some years.
In this situation, I installed R 3.3.1 and then entered "update.packages
()", however, "Proxy Authentification" window didn't show up and
failed to access the internet. Error messages are as below.
