How to extract website name from their links in R?

If we have a list of website links and we want to extract the website name from those links then it is a time-consuming task because we would need to copy each name one-by-one. Therefore, it is better to extract them using a function in R and save time. To extract the website name from the website link, we can use suffix_extract function of urltools package. This will extract the host, subdomain, domain and suffix. And it is known that the domain values are the website names.

Loading urltools package −

library(urltools)
