Introduction Quite often I see a question in a newsgroup or forum along the lines of: What is this thing called 'OOP'?
Creating R packagesPrevious: Writing R documentation filesPrevious: The R distribution itself includes about 30 packages. In the following, we assume that you know the library command, including its lib.
See Add-on-packages in R Installation and Administration. Other types of extensions are supported but rare: 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 packages, a zip file or tarball containing the files of an installed package which can be unpacked rather than installing from sources. A package is not 1 a library.
The latter is used in two senses in R documentation. A directory into which packages are installed, e. Installed packages may contain compiled code in what is known on Unix-alikes as a shared object and on Windows as a DLL.
The concept of a shared library dynamic library on macOS as a collection of compiled code to which a package might link is also used, especially for R itself on some platforms.
On most platforms these concepts are interchangeable shared objects and DLLs can both be loaded into the R process and be linked againstbut macOS distinguishes between shared objects extension.The Bach Foundation Code of Practice Introduction.
