Currently this is a valid option for g++ 5 and later and 2016 versions of the Intel and Solaris compilers. For earlier versions of g++ one could try -std=c++1y.

(13)

This is true for earlier versions of g++ such as 4.2.1, and also for commonly-used versions of the Solaris compiler CC.

(14)

Currently only GCC 6 and later, but this has been mooted for others.

For when features were supported, see https://gcc.gnu.org/projects/cxx-status.html#cxx11.

Suitable distributions include Strawberry Perl, http://strawberryperl.com/ and ActivePerl, https://www.activestate.com/activeperl.

The installer as puts links to R and Rscript in /usr/local/bin. If these are missing, you can run directly the copies in /Library/Frameworks/R.framework/Resources/.

(18)

The framework for R 3.3.x was named org.r-project.R.mavericks.fw.pkg: use pkgutil –pkgs | grep org.r-project to check for earlier versions of R.

(19)

More precisely, of the package of the same name: this means that installing a package for 3.3.x does 3.4.x does not remove an installation of the other series.

(21)

its binding is locked once the startup files have been read, so users cannot easily change it.

(22)

If a proxy needs to be set, see ?download.file.

for a small number of CRAN packages where this is known to be safe and is needed by the autobuilder this is the default. Look at the source of tools:::.install_packages for the list. It can also be specified in the package’s DESCRIPTION file.

(24)

or by adding it in a file such as etc/i386/Makevars.site, which does not exist by default.

(25)

Note that capitalization and version may differ from the Open Source project.

(26)

using a path containing spaces is likely to cause problems

(27)

They need to have been created using -headerpad_max_install_names, which is the default for an R package.

‘X/Open Portability Guide’, which has had several versions.

On some systems setting LC_ALL or LC_MESSAGES to ‘C’ disables LANGUAGE.

(30)

If you try changing from French to Russian except in a UTF-8 locale, you will most likely find messages change to English.

(31)

the language written in England: some people living in the USA appropriate this name for their language.

(32)

with Americanisms.

(33)

also known as IEEE 754

(34)

at least when storing quantities: the on-FPU precision is allowed to vary

(35)

e.g. Bessel, beta and gamma functions

(36)

including copying MkRules.dist to MkRule.local and selecting the architecture.

(37)

also known as IEEE 754

(38)

Note that C11 compilers need not be C99-compliant: R requires support for double complex and variable-length arrays which are optional in C11 but is mandatory in C99.

(39)

Examples are -std=gnu99, -std=c99 and -c99.

(40)

-std=c99 excludes POSIX functionality, but config.h will turn on all GNU extensions to include the POSIX functionality for R itself: this does not apply to badly-written packages. The default mode for GCC 5.1 and later is -std=gnu11, which currently includes the optional features R needs.

(41)

However, it is possible to break the default behaviour of glibc by re-specifying the gconv modules to be loaded.

(42)

specifically, the C99 functionality of headers wchar.h and wctype.h, types wctans_t and mbstate_t and functions mbrtowc, mbstowcs, wcrtomb, wcscoll, wcstombs, wctrans, wctype, and iswctype.

(43)

including opendir, readdir, closedir, popen, stat, glob, access, getcwd and chdir system calls, select on a Unix-alike, and either putenv or setenv.

(44)

such as realpath, symlink.

(45)

most often distributed as part of xz: possible names in Linux distributions include xz-devel/xz-libs and liblzma-dev.

(46)

sometimes known as PCRE1, and not PCRE2 which started at version 10.0.

(47)

but not a major version greater than 7 should there ever be one: the major version has been 7 since 2000.

(48)

for example to specify static linking with a build which has both shared and static libraries.

(49)

Such as GNU tar 1.15 or later, bsdtar (from https://github.com/libarchive/libarchive/, as used by FreeBSD and OS X 10.6 and later) or tar from the Heirloom Toolchest (http://heirloom.sourceforge.net/tools.html).

texi2dvi is normally a shell script. Some versions (including that from texinfo 5.2 and 6.0) need to be run under bash rather than a Bourne shell, especially on Solaris. Some of the issues which have been observed with broken versions of texi2dvi can be circumvented by setting the environment variable R_TEXI2DVICMD to the value emulation.
