What is 'WebScrapping' in 'R' language?

 Posted by Niladri.Biswas on 5/1/2013 | Category: Others Interview questions | Views: 953 | Points: 40

In webscraping, the user extracts information embedded in a web page available over
the internet and saves it into R structures for further analysis. One way to accomplish
this is to download the web page using the readLines() function and manipulate it
with functions such as grep() and gsub() . For complex web pages, the RCurl and
XML packages can be used to extract the information desired.
