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

? 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 ?
