Package development process
 |
 | This article provides insufficient context for those unfamiliar with the subject. (September 2010) |
A Software Package development process is a system for developing software packages. Packages make it easier to reuse and share code, e.g., via a software repository. A formal system for package checking can help expose bugs, thereby potentially making it easier to produce trustworty software (Chambers' prime directive). [1] This in turn can help improve productivity for people who produce and use software.
Discussion
In this context, a package is a collection of functions written for use in a single language such as Python or R, bundled with documentation. For many programming languages, there are software repositories where people share such packages.
For example, a Python package combines documentation, code and initial set up and possibly examples that could be used as unit tests in a single file with a "py" extension.
By contrast, an R package has documentation with examples in files separate from the code, possibly bundled with other material such as sample data sets and introductory vignettes. The source code for an R package is contained in a directory with a "DESCRIPTION" file and subdirectories "man" containing documentation files, "R", with files of code, and perhaps others. [2]
