R Tutorial For Absolute Beginners [2021]

Welcome to my R tutorial for absolute beginners :-)
My main programming language is Python but I had to do some R while graduating and meanwhile I am really enthusiastic about this language and already did some projects with it.
A lot of quantitative trading strategies but also ML algorithms/ Data Science / Data Analysis Projects are written in R and you don't want to miss out at least having a basic understanding of the language.
I can only recommend to have a look and write some programs in it no matter if you are interested in Finance , Data Analysis or Data Science!
I hope with this tutorial I can give you an overview of the - in my perception - most important basics so that you can start out writing some programs in it.

Let me know your thoughts or questions in the comments below.

this is literally my last-minute tutorial for my next job interview. Thank you so much.

[aryantnigam]

what our teacher taught in 40 days u did it in 40 mins truly commendable job

[elizabethbattley]

Mate I just want to say that this is one of the best videos I have seen on learning the basic of R. It is my first time trying to learn it for my master project and it has been a pleasure to watch. Very informative and easy to follow so thank you so much for taking the time to make it. Can't put into words how much this has helped me and has put me on my way to complete my masters! Amazing work

[mvr]

Thank you, this helped a lot to kickstart understanding R.

[kokoninja]

This was a pretty cool tutorial! Short and sweet! Moreover, it was really easy to follow! I enjoyed it very much! Thank you for providing this tutorial!

[pratiksikdar]

I am very new to this Programming Language, your teaching really helped me a lot!

[ibrahimdiiriye]

This video taught me a lot, appreciate your work well done👍.

[mariocivil]

Very useful!!! Thanks and keep it up!!!

Hello,
Thank you very much for all your efforts, it is greatly appreciated.
I'm glad to see that you teach people about R as well.
Indeed I've been working as a R shiny developer for several months and I master it quite well.
I wonder if it's not possible to reproduce everything you did on algo trading with binance APIs on an R environment? I am quite pessimistic about this because Binance provides all the doc on python...
Do you have any Idea ?
Thank you again!

[mangeshw]

Thanks bro god bless u make one vedio on Fibonacci level with EMA moving average that generates buy and sell

Hello, professor
I would like to know if you did a video about how to use penguins dataset who can help need to do this problem.
Using the penguins dataset, generate a histogram for flipper

length. Calculate the mean, median, variance, standard

deviation, and Q1 and Q3 of the flipper length variable.

Determine the 90th percentile of the flipper length variable

and calculate the Z-score for a penguin who has a flipper of

length 220 mm.

After installing R studio, it shows that "do you want this app to make changes to your device". I tried clicking on both yes and no but it's not opening. What to do? Could you please help.

[mustafanawaz]

I am unable to open csv file on r studio.

[fatoukabre]

I am a newbie as well, and really appreciate your effort in breaking things down. I am just mimicking the course along, and somehow, I don't seem to find the right directory to import my csv file. My file is stored in a folder on my desktop. How do I import it into R studio and continue working?
Thank you for the help.

Hi just came across your channel & watched 3, 4 videos of yours.
I started with python for Data Science but moved to R in a year & fell in love with the way R & shiny can play with the data and so never felt like going back to python again but:

1. In India no (hardly any) company want to use R because its mostly a software/service industry here. R is mostly used in Research/academics so this backfired on me.

2. I am looking to practice some trading & saw your Python videos on same. Is there any advantage in any language when it comes to Stock market or trading ?? (R has quantmod, tidyquant etc. packages which I know about but does python have any edge over them ?)

did martin and lisa repaid the money? if yes, put the other ones in the example :D
