[R] Question about proxy setting of R
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. ----------------------------------------------------------------------------------------------------------------------------> update.packages(ask='graphics',checkBuilt=TRUE)--- Please select a CRAN mirror for use in this session --- Warning: failed to download mirrors file (cannot open URL 'https://cran.r-project.org/CRAN_mirrors.csv'); using local file 'C:/PROGRA~1/R/R-33~1.2/doc/CRAN_mirrors.csv' Warning: unable to access index for repository https://cran.ism.ac.jp/src/contrib: ? cannot open URL 'https://cran.ism.ac.jp/src/contrib/PACKAGES' Warning: unable to access index for repository http://www.stats.ox.ac.uk/pub/RWin/src/contrib: ? cannot open URL 'http://www.stats.ox.ac.uk/pub/RWin/src/contrib/PACKAGES' Warning message: In download.file(url, destfile = f, quiet = TRUE) : ? cannot open URL 'https://cran.r-project.org/CRAN_mirrors.csv': HTTP status was '407 Proxy Authentication Required' ---------------------------------------------------------------------------------------------------------------------------- Strange to say, R 3.0.2 is able to access to the internet, and R 3.3.1 shows collect proxy setting in ".Rprofile"? by "Sys.getenv("http_proxy")" From internet information, I added "http_proxy_user=ask" to ".Rprofile", or " --internet2" to the desktop icon of R 3.3.1, ending up in the same result. Please show me the way of proxy setting of R 3.3.1.
