Martin Morgan, I tried an HTTP mirror and it worked.
What could be the problem and how to fix?
The problem is in the warning message
1: In download.file(url, destfile = f, quiet = TRUE) :
URL 'https://cran.r-project.org/CRAN_mirrors.csv': status was 'Problem
with the SSL CA cert (path? access rights?)'
and an easier way to reproduce / troubleshoot the problem is
download.file("https://cran.r-project.org/CRAN_mirrors.csv";,
tempfile())
The details of this process are described in ?download.file. My guess
would be that you have 'libcurl' available
> capabilities()["libcurl"]
libcurl
TRUE
that it supports https (mine does, in the protocol attribute):
> libcurlVersion()
[1] "7.35.0"
attr(,"ssl_version")
[1] "OpenSSL/1.0.1f"
attr(,"libssh_version")
[1] ""
attr(,"protocols")
[1] "dict" "file" "ftp" "ftps" "gopher" "http" "https"
"imap"
[9] "imaps" "ldap" "ldaps" "pop3" "pop3s" "rtmp" "rtsp"
"smtp"
[17] "smtps" "telnet" "tftp"
and that you have outdated or other CA certificates problem, with some
hints for troubleshooting in the first and subsequent paragraphs of the
'Secure URL' section.

Also, should I ignore the warning about ignoring environment value of R_HOME?
Thanks.

setInternet2() first thing after launching R might fix that.

Hello.
I've tried to run R, but I receive many warnings and can't do simple
stuff such as installing packages.
Here's the full log when I run it.

Does anyone know what could be wrong here?
Thanks a lot.
