Sources, binaries and documentation for R can be obtained via CRAN<\/a>, the \u201cComprehensive R Archive Network<\/a>\u201d whose current members are listed at https:\/\/CRAN.R-project.org\/<\/a> mirrors.html.<\/p>\n The simplest way is to download the most recent R-x.y.z.tar.gz file, and unpack it with<\/p>\n tar -xf R-x.y.z.tar.gz<\/p>\n on systems that have a suitable1 tar installed. On other systems you need to have the gzip program installed, when you can use<\/p>\n gzip -dc R-x.y.z.tar.gz | tar -xf –<\/p>\n The pathname of the directory into which the sources are unpacked should not contain spaces, as most make programs (and specifically GNU make) do not expect spaces. If you want the build to be usable by a group of users, set umask before unpacking so that the files will be readable by the target group (e.g., umask 022<\/a> to be usable by all users). Keep this setting of umask whilst building and installing.<\/p>\n1.1 Getting and unpacking the sources<\/h5>\n
