[R] Udpate R under a proxy

[Liaw, Andy]

This is what I just tried (thanks, Dirk!):

Start R and then Sys.putenv("http_proxy", "whatever"), options(download.file.method="wget") doesn't work.

Open up a command prompt, define http_proxy there, then run Rgui.  Set options(download.file.method="wget").  This works.

Perhaps you can define http_proxy in Renviron.  I have not tried that.
