Dear Jim,
Thanks to your advice, "Proxy Authentification" window�showed up, however, I couldn't access to 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 (scheme not supported in 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: � scheme not supported in URL 'https://cran.ism.ac.jp/src/contrib/PACKAGES' Proxy authentication failed: � � � � please re-enter the credentials or hit Cancel------------------------------ ------------------------------ ------- I assume the proxy server is only available for "http", not "https". What should I do ?
