How to create variables and lists in R | R Tutorial #4

In this video, I will show you how to create variables and lists in R. A variable is an object that can store values, for example, we can assign a single color value "blue" to a variable called "color. On the other hand, a list allows a variable to store a collection of values, for example, we can store several color information such as "blue", "green" and "red" to a single variable.

Thus, we have the following
Single-valued variable 👉 color = 'blue'
Multi-valued variable 👉 colors = ['blue', 'green', 'red']

Hi, Professor. I am super glad that I found your channel. I have shared this with my friends. The highest respect for your videos!!!! One bold request: could you please make a video explaining how to design a conventional questionnaire (a question per time or per page) with the shiny package? There are some incomplete web articles and ZERO videos introducing this! It would be a great contribution to the whole community if you can make a video about the questionnaire designing. Thank you very much.

Friend: What is the biggest difference between R and other programming languages?
Me: It starts counting from 1.

Hi, great video! Tell me something: I have a laptop with AMD Ryzen 5 GPU. I am trying to build things that need CUDA. Is there any way to run it on a AMD GPU? Or it there any alternative that doesn't include buying a new laptop? Thanks
