Beginner’s Guide on Web Scraping in R (using rvest) with hands-on example

I was going through the article " Beginner’s Guide on Web Scraping in R (using rvest) with hands-on example" and trying to recreate the magic that author did. I have few questions:

  1. when I click and try to get the code in CSS, its not showing same as shown int he article. if i copy paste author’s code it works but if i use the one that is shown to me that doesn’t work.

e.g. in description its showing as “.text-muted” but author has used ‘.ratings-bar+ .text-muted’ how did he get .ratings-bar+., what does it mean

  1. can someone share R scrapping link where a lot of manual things that is being done by author like replacing values and all is not being done.
