In order to access CRAN packages from within R on OSX I've been using
Sys.setenv(http_proxy="http://blah_blah:1234/")
as the first command in the R GUI for a while, but would really like to set this proxy automatically.
I've tried unsuccessfully to get the same command to work in a .Rprofile 开发者_如何学Cfile in ~/
I've also tried http_proxy="http://blah_blah:1234/", but this fails too.
The error I get when I try to view packages is a drop-down window that says:
Fetching Package List Failed
Please consult R Console output for details
The GUI then gives:
Error in read.dcf(file = tmpf) : Line starting '<head> ...' is malformed!
The .Rprofile file itself seems to be loading (checked using cat("my profile works\n"))
Couldn't you just use .First ?

This thread appears first when searching for setting R proxy on OS X, so here's what I use in my .Rprofile:
Sys.setenv(http_proxy=system("networksetup -getwebproxy Ethernet | awk {'print $2'} | awk {'getline l2; getline l3; print \"http://\"l2\":\"l3'} | head -n 1",intern=TRUE))
Change Ethernet to Airport if necessary.
Credit for the awk part goes to Chealion
I think I have managed to solve this using trial and error...
A combination of .First and Sys.setenv() works.
If anyone has any ideas I'd be interested to know why.
