Hello everyone! Good Morning...
I would like some tips on how to get data from a web page  within R.
I made a few attempts, but I was unsuccessful because I have little
knowledge of the http / https protocol.
If anyone can provide any guidance, I would appreciate it very much.
My difficulty is because this page appears to be a front end that
Hm personally I can only give unhelpful help but I can give (1) some general pointers that have helped me, and (2) a possibly different approach.
What usually works for me when dealing with getting data from the web involves using the developer tools in a web browser. If you can see what requests your browser makes, and the server responses you get, you should be able to reproduce them using the httr package (or rcurl, etc) and parse the response using rvest.
It *Looks* like you're trying to get stock price data for IBOVESPA - is this the same thing as ^BVSP ? if so, have you tried using the quantmod package?
getSymbols("^BVSP", src = "yahoo") # this will automatically get the data, and assign it to a variable called "BVSP"
