So compiling a package may come to mean byte-compiling its R code. There is also the possibility of ‘byte’ compiling the R code in a package (using the facilities of package compiler): nowadays this is enabled by default for all packages. Installing a source package which contains C, C++ or Fortran code will involve compiling that code.

Compilation is not a correct term for a package.

Source packages (and most often tarballs) can be checked, when a test installation is done and tested (including running its examples) also, the contents of the package are tested in various ways for consistency and portability. This involves taking a source directory and creating a tarball ready for distribution, including cleaning it up and creating PDF/HTML documentation from any vignettes it may contain.

The most common is installation which takes a source package and installs it in a library using R CMD INSTALL or install.packages.

There are a number of well-defined operations on source packages. On most platforms these concepts are interchangeable (shared objects and DLLs can both be loaded into the R process and be linked against), but macOS distinguishes between shared objects (extension. 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. Installed packages may contain compiled code in what is known on Unix-alikes as a shared object and on Windows as a DLL.

That used by the operating system, as a shared, dynamic or static library or (especially on Windows) a DLL, where the second L stands for ‘library’.usr/lib/R/library: in that sense it is sometimes referred to as a library directory or library tree (since the library is a directory which contains packages as directories, which themselves contain directories). A directory into which packages are installed, e.g.It seems to stem from S, whose analogues of R’s packages were officially known as library sections and later as chapters, but almost always referred to as libraries. 1.5.6 Namespaces with S4 classes and methodsġ although this is a persistent mis-usage.
