Get the files of LDbase projects, datasets, code and documents

Lists the files of each LDbase link: for a project, every dataset, code and document in its hierarchy (child projects included); for a single dataset, code or document, its own file. A DOI is first resolved to the page it leads to. LDbase has no API, so this reads the public pages (one request per project or item). Items stored elsewhere (LDbase's "external link" option) have no file here and are not listed.

Usage

ldbase_info(ldbase_url, id_col = 1, pb = NULL, cache = FALSE)

Arguments

ldbase_url: a vector of LDbase URLs or DOIs, or a table containing them (e.g. from ldbase_links())
id_col: the index or name of the column that contains the URLs, if ldbase_url is a table
pb: a progress bar from pb(), or NULL to create one
cache: if TRUE, a listing is read from / written to the persistent repository-listing cache (see repo_info_cache_clear())

Value

a data frame with one row per link: ldbase_url, ldbase_page (the resolved page), ldbase_type, title, doi, license (the licence of the item, or every distinct licence of a project's items joined by "; "), a list-column files (a data frame per link with file_name, file_path, file_url, item_type, item_url) and error (NA, or why the link could not be listed)

Examples
