El curso es bueno y el profesor sabe del tema, sin embargo las sintaxis están desactualizadas,ya no scrapean las páginas seleccionadas debido a que están ya han cambiado su estructura por lo que requieren actualización ya que ninguna sirvió, a su vez no estaban adjuntas las sintaxis del último ejercicio de udemi

The course exceeded expectations: in just a few hours it teaches many useful things.

More than I spected.

By Marcus Jones on 7/25/2022

Mikkel is a gifted teacher. However, the course is in need of some updating. Two of the web sites and one of the packages used in the course have changed. I was still able to complete the course but needed extra time to figure out what was broken and adjust for the changes. Still there's lots to learn and the information is still reliable (hence 3 stars). I even learned one or two data munging tricks along the way. The XHR api trick was also a real eye-opener.

This is looking great so far. I love using R but even on the wrangling I have learned a few things even after the first chapter. Very keen to learn RSelenium, I have used Selenium with Python but want to use it in R.

By David Armstrong on 11/14/2021

So far, the instructor is quite good and provides good resources, but the website being scraped has changed, so some of the examples do not work as intended.

By Alexandre George Lustosa on 10/10/2021

This is for sure the best webscraping course in UDEMY! The instructor gives all the details of the processes carried out in a simple and effective way!

By Rodrigo Estrella on 1/19/2021

I would have liked to see more about scraping using selenium. Nevertheless it was a well explained course

By Charles C on 12/23/2020

Focused and hands-on approach to the subject. Especially useful is the XHR network API approach. The course is a concise treatment and nicely paced. Recommended.
