Exercize

Use the Google doc to obtain all the addresses of the websites created in class.

For all the webpages:

  • extract the content of the highest header. (h1 is the highest header. If h1 is missing, then take the h2, etc. If there's no header, report that the header is missing. If there are duplicates, keep all content.)
  • format the resulting content in a data.frame with one column for the website url, and one column for the content of the header.
