Either a path to a local source repository, or a local '.tar.gz' file containing code for an R package.

Value

List of statistics and data on function call networks (or object relationships in other languages). Includes the following components:

  1. loc: Summary of Lines-of-Code in all package directories

  2. vignettes: Numbers of vignettes and "demo" files

  4. desc: Summary of contents of 'DESCRIPTION' file

  5. translations: List of translations into other (human) languages (where provides)

  6. objects: A data.frame of all functions in R, and all other objects (functions, classes, structures, global variables, and more) in all other languages

  7. network: A data.frame of object references within and between all languages; in R these are function calls, but may be more abstract in other languages.

s <- pkgstats (path)
