R programming for beginners: using functions and objects in R

R Programming is easy. In this video, you'll learn about how to work with data by applying functions to objects. Understanding this process is the first step in learning R programming.
This is part of the "R programming for beginners" series that will teach out how to analyze data and do statistical analysis with quantitative data.
Statistics doesn't have to be difficult.

I swear, this is the only guy on the entire web that explains R clearly and concisely. Some people are just born to teach and pass on their knowledge. Great work.

You're back! We missed you so much.
As always, thank you for your lesson, I really appreciate it.

Cheers! Absolutely love these videos; they make my life so easy. Decided to start using R out of the blue, since SPSS is kinda clunky when it comes to functions that aren't default and the SPSS' own syntax is just terrible.

Your videos have made my doctoral thesis regarding lung cancer progress so much in an instant! Kinda fun that I managed to find your channels, which are statistics, R and medical research oriented!

Sir, I'm more familiar with other software, but, as a learning of R, I found the video so clear. I followed and pratice every step and I also found what is shown in the screen. I didn't work with raw data from filter, but I found for example the value of 50, 36, ...how magic is? Could you/we explain why those values appeared without using raw data? Could you next time show how to draw figures from fresh, dry weight of plants (just an example)? Stacked bar chart? Thank you for those demonstrations. Really appreciated Man.

Awesome presentation, Boss of R"
which software you use to edit your record please?

[acada]

Your videos are quite explanatory. You're a great teacher, keep it up.

Nice presentations. I have a simple question what theme are you using for your code? It is nice and sharp. Also, do you recommend using rainbow parens. I really like those for debugging.

Thanks, Greg. This is a very nice introduction to me, using functions.

[BilluAck]

Was waiting for your video from quite a long thank you Sir

[jeanhwang]

Thanks so much for your R programming series for beginners! I've finished ten of them and feel much better with R, at least I am more clear and confident in dealing with R. If possible, looking forward to others series like how to use R in data mining, such as to plot and analyze a decision tree. Anyway, thank you again for your teaching and time!

I see a favorite actor Jason Statham 😁teaching me R program. Thank you Prof Greg, you make R look easy. I'm hooked to your style of teaching. 👏👏👏👏

[MBG_Broker]

These videos are so great, it is a shame that they do not come out more often. :)

[rowlinmoe]

He talks really fast and is still easy to listen to, that's very weird lol.
Wonderful teacher, I only wish the videos were longer

[gretek.]

Please come back, your explanations are heavenly

[tanyacoonan]

That was very helpful. Thank you. If I have a dataset inputted into R like yours, how do I encode the variables (such as speed and distance) as factors? What does this mean?
