The R distribution itself includes about 30 packages. In the following, we assume that you know the library command, including its lib, doc resume perl.
loc argument, and we also assume basic knowledge of the R CMD INSTALL utility. Once a source package is created, it must be installed by the command R CMD INSTALL, doc resume perl.
See Add-on-packages in R Doc resume perl and Administration. Other types of extensions are supported but rare : See Package types.
Some notes on terminology complete this introduction. These will help with the reading of this manual, and also in describing concepts accurately when asking for help. A package is a directory of files which extend R, a source package the master files of a packageor a tarball containing the files of a source package, or an installed package, the result of running R CMD INSTALL on a source package.
On some platforms notably macOS and Windows there are also binary packagesa zip file or tarball containing the files of an installed package which can be unpacked rather than installing from sources, doc resume perl.
A package is not 1 a library. The latter is used in two senses in R documentation. The concept of lazy loading of code or data is mentioned at several points.
This is part of the installation, doc resume perl, always selected for R code but optional for data. When used the R objects of the package are created at installation time and stored in a database in the R directory of the installed package, being loaded into the session at first use.
Doc resume perl makes the R session start up faster and use less virtual memory. For technical details, see Lazy loading in R Internals. CRAN is a network of WWW sites holding the R distributions and contributed code, especially Doc resume perl packages. shtml submitting. Next: Configure and cleanupPrevious: Creating R packagesUp: Creating R packages [ Contents ][ Index ].
The package subdirectory may also contain files INDEXconfigurecleanupLICENSELICENCE and NEWS, doc resume perl. md 2or ChangeLog will be ignored by R, but may be useful to end users. The utility R CMD build may add files in a build directory but this should not be used for other purposes. The NAMESPACE file is described in the section on Package namespaces. The optional files configure and cleanup are Bourne shell scripts which are, respectively, executed before and if option --clean was given after installation on Unix-alikes, see Configure and cleanup.
The analogues on Windows are configure. win and cleanup. html Documentation. The package subdirectory should be given the same name as the package.
Because some file systems e. For example, if you have a package named foodo not also create a package named Foo. Also, file names in the same directory must not differ only by case see the previous paragraph. For maximal portability filenames should only contain only ASCII characters not excluded already that is A-Za-z In addition, packages are normally distributed as tarballs, and these have a limit on path lengths: for maximal portability bytes.
A source package if possible should not contain binary executable files: they are not portable, and a security risk if they are of the appropriate architecture. R CMD check will warn about them 4 unless they are listed one filepath per line in a file BinaryFiles at doc resume perl top level of the package. Note that CRAN will not accept submissions containing binary files even if they are listed. The R function package. skeleton can help to create the structure for a new package: see its help page for details.
Next: LicensingPrevious: Package structuredoc resume perl, Up: Package structure [ Contents ][ Index ]. Fields start with an ASCII name immediately followed by a colon: the value starts after the colon and a space.
Continuation lines for example, for descriptions longer than one line start with a space or tab. Field names are case-sensitive: all those used by R are capitalized. This should contain only ASCII letters, numbers and dot, have at least two characters and start with a letter and not end in a dot. It is not a decimal number, so for example 0. Some package listings may truncate the title to 65 characters. It should use doc resume perl case that is, use capitals for the principal words: tools::toTitleCase can help you with thisnot use any markup, not have any continuation lines, and not end in a period unless part of ….
Do not repeat the package name: it is often used prefixed by the name. Refer to other packages and external software in single quotes, and to book titles and similar in double quotes. One can use several complete sentences, but only one paragraph. It should be intelligible to all the intended readership e. for a CRAN package to all CRAN users. This field should also be used for explaining the package name if necessary. URLs should be enclosed in angle brackets, e. Note that all significant contributors must be included: if you wrote an R wrapper for the work of others included in the src directory, you are not the sole and maybe not even the main author.
It should doc resume perl end in a period or comma. This field is what is reported by the maintainer function and used by bug. For a CRAN package it should be a personnot a mailing list and not a corporate entity: do ensure that it is valid and will remain valid for doc resume perl lifetime of the package.
Note that the display name the part before the address in angle brackets should be enclosed in double quotes if it contains non-alphanumeric characters such as comma or period.

If present, the collate specification doc resume perl list all R code files in the package taking possible OS-specific subdirectories into account, see Package subdirectories as a whitespace separated list of file paths relative to the R subdirectory.
Paths containing white space or quotes need to be quoted. This can be overridden by installing with flag --no-byte-compile. This can be overridden by by the flags --use-LTO and --no-use-LTO. This field was introduced in R 3. This should only be used exceptionally, for example if the PDFs include doc resume perl figures which are not part of the package sources and hence only in packages which do not have an Open Source license.
The utils package is always implicitly appended, doc resume perl. See Non-Sweave vignettes for details. Rd files, doc resume perl. The examples are assumed to be in this encoding when running R CMD checkand it is used for the encoding of the CITATION file. Only encoding names latin1latin2 and UTF-8 are known to be portable, doc resume perl. Do not specify doc resume perl encoding unless one is actually needed: doing so makes the package less portable.
If a package has a specified encoding, you should run R CMD build etc in a locale using that encoding. This is used by install. html ; the former refers to the version. The subject classifications should be comma-separated lists of the respective classification codes, e.
Macro definitions in individual. Rd files in the man directory are loaded last, and are local to later parts of that file. In case of duplicates, the last loaded definition will be used. Packages using Rd macros should depend on R 3. There is no restriction on the use of other fields not mentioned here but using other capitalizations of these field names would cause confusion.
