Rvest vs Rselenium
Its very often the case that data crawling needs to accomodate cookie requests
from the website and/or by pass login authorizations.
While rvest is a great tool to process html text, accomodating cookies and login
requests can be quite troublesome.
The main problem comes with the internals of read_html() function which
builds on curl type of requests. This connection is often stateless and
may result to 301 http errors.
