I recently compiled and installed R 3.2.2 on an RHEL 6.5 system. Upon installation, I tried
$ R-3.2.2/bin/R R version 3.2.2 (2015-08-14) -- "Fire Safety" .... > update.packages() --- Please select a CRAN mirror for use in this session --- Error in download.file(url, destfile = f, quiet = TRUE) : unsupported URL scheme HTTPS CRAN mirror .... Selection: 14 Warning: unable to access index for repository https://cran.mtu.edu/src/contrib However, choosing '18: (HTTP mirrors)', which then presents a different menu of download location choices, and selecting one of those seems to work, as does specifically naming a http URL, e.g., update.packages(repos = "http://cran.mtu.edu/"). Is the defaulting to the https URL-type a new behavior? Did I miss including some library, so https is not included? My configure line was $ ./configure --prefix=/tmp/bennet/local --mandir=/tmp/bennet/local/man \ --enable-R-shlib --without-x \ --with-blas="-L/usr/cac/rhel6/intel-xe-2015/mkl/lib/intel64 -lmkl_gf_lp64 -lmkl_sequential -lmkl_core" and I have $ rpm -qa | grep curl curl-7.19.7-46.el6.x86_64 libcurl-devel-7.19.7-46.el6.x86_64 libcurl-7.19.7-46.el6.x86_64 installed. If https is the default URL-type, is there some configuration I need to do to not get the unsupported URL scheme message? Is there a way to globally set the URL-type to http instead? I recompiled R 3.1.1 to check, and it doesn't seem to default to https. Sorry if this is covered somewhere, pointers to appropriate documentation will be appreciated.
