R package predatory. Tools for Detecting Predatory Publishers and Journals. Allows the user to check and find (allegedly) predatory journals based on Beall’s list available at <https://scholarlyoa.com/>. As part of a research project, the data from the website has been scrapped with web scraping algorithms and manual work. The package includes a search function and direct access to this database of predatory journals. The use of this tool should facilitate the detection of predatory publications by researchers and librarians.
