Getting started with R: Basic Arithmetic and Coding in R | R Tutorial 1.3 | MarinStatsLectures

In this R video tutorial, we learn how to assign values to objects in R, how to turn R into a fancy calculator and perform basic arithmetic functions (+, -, *, /) in R, and more.

In this R video tutorial, you will learn:

►How to assign values to object is R using the equal sign (=) or less than sign with dash
►How to use ls function to see the data stored in R
► How to use rm function to remove an object in R
►How to add, subtract, multiply, and divide in R
► How to use sqrt function in R to find the square root of an object
► How to use log function in R to calculate logarithms
► How to use exp function in R to take the exponent or anti-log
► How to use abs function in R to calculate the absolute value
► and a few handy keyboard shortcuts in R

Very good videos Marin - just the right pace and amount of description. No wasted words and totally clear. Your videos are a model of how tutorials should be presented.

[davka]

I love the phase you are teaching. Very concise and to the point. thanks very much

[abrahammusembi]

wow what a wonderful introduction.very encouraging. You've created a positive attitude towards R, it seems to easy for me. Thank you.

[eamaning]

Thanks a million Prof. Marin.
A big thank for all your awesome videos on R and the others. It has really helped me in a lot of ways. God bless you!

[davidlinnemann]

I have been trying to fine an R Programming video series for the last few months. I finally found a winner! Marin, you saved me!!

[marinstatlectures]

Thanks Hasan! I agree with you, it's a lot more effective to learn by doing, rather than to try and learn by observing. Thanks for watching!

[cyanideu]

Thanks a lot Mr.Martin, I look forward for more videos as am new to this software and want to do some research work with my husband using r program.

[DeepakGupta-qeqq]

You are Awesome Marin!!!. Really great videos...Short and sweet.

[bharatarse]

Thanks Mike.. Just started with R.. I will watch your all video one by one to learn R with fun.. I like the way you are explaining everything..

[EunsoothePooh]

Thank you so much! I've been looking for ways to learn R and this is super helpful. Thank you! 

[VetDev]

Just wanted to thank you for all your hard work, and that your videos have been very easy to follow. Great work.

[AfsanehKasiri]

Thanks, this video was really helpful.

[hasank]

Thanks for posting these video. This is exactly what I was looking for. I have no desire for learning stats on its own and then apply that knowledge to statistical packages such as R and Matlab, by learning how to program it. Why not learn stats on a program like this to begin with.

[barbarabustamante]

Hi Marin! Wanted to say thank u again!  For thaking the time to share your knowledge!

[yoman]

i really enjoyed that - Thanks for sharing. It's of great help.

[kaushalpandey]

i'm beginer, currently started to learn R, had search and seen lot of video's. Finally i have to started from this one thanks

[dexterthiam]

Thanks Marin! Learnt this in University many years ago but forgotten quite a lot of them as I don't have any chances to use them after that. Wanted to pick up the skills again. Thanks for your videos!
