[R] Reading from a webpage

[Vahid Borji]

Hi there,

I am using R. I want to save a text, which is inside the following webpage,
in a variable, and then want to answer some questions.

http://en.neyshabur.ac.ir/en/119-about-city-of-neyshabur/1232-city-of-neyshabur

My questions are:

1) How many words do exist in the text (of the webpage)?

2) How many characters are there in the text (of the webpage)?

3) I want to find (specify) words (of the text) that have more than 9
letters. How can I do it?

4) I want to find words that are repeated at least four times in the text.
How can I do it?

5) Assume the words of the text are typed vice verse (from end to first),
how can I edit it?
