Check Documented Functions in a Package

Lists all documented functions in a package and checks their documentation elements for potential issues. The following checks are performed:

1. Title is present and doesn't start with regex "Function".

2. Description is present and doesn't start with "This function".

3. Value is present.

4. Example is present.

Usage

check_pkg_docs(pkg = NULL, unload = TRUE, reload = TRUE)

Arguments

pkg

The package name. If NULL, the package name is inferred from the DESCRIPTION file in the current directory or any parent directory. If no DESCRIPTION file is found, the function stops with an error message.

unload

Whether to try to unload a potential currently developed package using devtools::unload() before checking the documentation. Required when the package was loaded with devtools::load_all() as the documentation database only exists for installed packages. If the unloading fails, the function silently continues, as the unloading is only necessary for checking the documentation of currently developed packages.

reload

Whether to reload the package using devtools::load_all() after checking the documentation.

Value

Returns a dataframe with columns title, description, value, examples and rows corresponding to the documented functions in the package. Each cell contains a string describing the check result for the corresponding documentation element of that function.

Examples

df <- check_pkg_docs("tools")
try(df <- check_pkg_docs())
