Check Package URLs
Description
Check URLs in package sources.
Usage
check_package_urls(dir, verbose = FALSE)
Arguments
dir |
a character string specifying the path to a package's root source directory. |
verbose |
a logical indicating if output should monitor check progress. |
Details
Checking URLs is performed in parallel using curl (so this must be installed for checking).
The URLs checked are extracted from the package ‘DESCRIPTION’
(‘Description’, ‘URL’ and ‘BugReports’ fields), Rd,
‘CITATION’ and ‘NEWS.md’ files, if package xml2 is
installed also from the ‘.html’ files in ‘inst/doc’, and if
additionally pandoc is available on the system the
‘README.md’ and ‘NEWS.md’ files.
For efficiency reasons, URLs are first checked using ‘HEAD’ requests, and the ones with non-OK (200) status codes re-checked via ‘GET’ requests (unfortunately, ‘HEAD’ requests are not always honored appropriately).
Value
A data frame inheriting from class check_url_db with
information on the URL check problems found.
Note
This functionality is still experimental: interfaces may change in future versions.
