Examples of CRAN in a sentence
Note that ‘https:’ is required2, and that the SSL certificate for the Subversion server of the R project should be recognized as from a trusted source.Note that retrieving the sources by e.g. wget -r or svn export from that URL will not work (and will give a error early in the make process): the Subversion information is needed to build R.The Subversion repository does not contain the current sources for the recommended pack- ages, which can be obtained by rsync or downloaded from CRAN.
Sources, binaries and documentation for R can be obtained via CRAN, the “Comprehensive R Archive Network” whose current members are listed at https://CRAN.R-project.org/ mirrors.html.
There are about 25 packages supplied with R (called “standard” and “recommended” packages) and many more are available through the CRAN family of Internet sites (via https://CRAN.R-project.org) and elsewhere.

Adding all the packages needed to check CRAN increased this to about 600MB.
One can tar an existing installed package, or use R CMD INSTALL --build.However, there are some important details.•Current CRAN ‘x86_64’ macOS distributions are targeted at High Sierra so it is wise to ensure that the compilers generate code that will run on High Sierra or later.
Most are available for download from CRAN (http://CRAN.R-project.org/ and its mirrors), and other repositories such as Bioconductor (http://www.bioconductor.org/).
If the package depends on a version of R later than the one in use, it is possible that an earlier version is available which will work with your version of R: for CRAN look for ‘Old sources’ on the package’s CRAN landing page and manually retrieve an appropriate version (of comparable age to your version of R).

It has been supported by the GCC and LLVM projects for some years with diverging implementations.LTO support was added in 2011 for GCC 4.5 on Linux but was little used before 2019: compiler support has steadily improved over those years and --enable-lto=R is nowadays used for some routine CRAN checking.
