Adding web scraping into R-Instat

[rdstern]

This web site introduces (polite) web scraping in R. Web scraping is a useful topic to introduce in R-Instat. How do we do it? In the first instance I propose we could adapt his R commands and use them in a series of scripts?

That would be a good test of the script window. I wonder if they would work? Then we could discuss whether we could make this any easier, or whether this might stay largely a task through scripts?

There are 8 packages used and 6 are already in R-Instat. One other is rvest, which is also used in the web scraping chapter
of the Introduction to Data Science book. The other is called polite.
