Which of the following package is used for reading HTML and XML data?

httr
http
httx
all of the mentioned

The correct answer is: A. httr

httr is a package for making HTTP requests in R. It provides a high-level interface for making requests, as well as a low-level interface for more control. httr can be used to read HTML and XML data from the web.

The other options are incorrect.

  • http is a package for making HTTP requests in R. However, it is not as high-level as httr, and it does not provide as much functionality.
  • httx is not a package in R.

I hope this helps!
