Variables, Control structures & Functions - Lecture 2 - Data analysis using R

Learn about variables, control structures, functions, brackets, distributions, and other basic elements of the R language for statistical computing. During this second lecture, we'll discuss the answers to lecture 1, and go into more detail about programming your own data analysis in the R language. Directly to the answers of assignment 1 at 00:16:46, or to the start of lecture 2 at 00:53:14

So please be aware that parts of this lecture are difficult and relate to computer science theory... Many of these topics will come back in future lectures, but I discuss them in the second lecture, so in follow up lectures there is more time for examples on these complex topics, without having to discuss them in detail again.

Hello teacher, thank you so much for your videos..
Unfortunately i'm unable to access to your website.. it worked a couple of days ago 😮‍💨

Have you also covered time series analysis in this course?

Hi Professor,
i think your website might be down.
Could you reboot it?
