Understanding set.seed in R: Ensuring Reproducibility in Data Analysis

Have you ever wondered what set.seed() does in R? What is it used for? Ever wondered why your UMAP or t-SNE appears different everytime you run it?
In this video I have demonstrated 2 quick examples to explain how set.seed() can be used to make your code reproducible.
I hope you find this video helpful! Leave your thoughts in the comment section below!

Thank you so much for such a wonderful explanation. This was my first time visiting your channel, and I found some very interesting and important topics that may be helpful as I'm a biostatistics student. It's very difficult to find any topics related to biostatistics on CZcams, so I found your channel best suited for me.

Thanks, i didn't understood before seeing this video that we need to run set.seed every time before a random generation, i thought 1 time was enought at the begenning of the code

[@yuxinhu4764]

are there any rules for choosing a seed? can I use any number I like as a seed as long as I use the same seed every time?

[@shatadrupalable]

what is the significance of intital seed value used (123).

[@nancyyan7365]

It looks this is just showing how a seed valued used in the UMAP package
