You literary explain every question i've had about R in 3min! I'm taking a class this summer and we have to use R I'm a little nervous because of the programming language aspect, but you've convinced me it will be so much better than data messaging in Excel and Jump!
This is the shortest and sweetest video giving sneak peek into R Programming. Greg is successful in creating enough interest to start learning R. And yes R Programming is not scary and comes across to be intuitive. Thanks Greg.
Thanks, I'm sharing this channel with my friends, we are all soil scientists and are in the process of learning R and these videos are awesome! We are data heavy and have had limited means to analyze our data other than excel; R will transform how we analyze and explain our data.
Hi Van - thanks for the comment. I'm in the same boat. I work in public health (very data heavy). Looking forward to going on this journey with you. Let me know if there are particular videos that you'd like to see.
Your enthusiasm and your smile is what caused me not to get an anxiety attack or palpitations beating out of my chest. I have never ever been so nervous from course material in my life as I take statistics for the first time in my life. I really hope our professor allows us to use R instead of Microsoft Excel :@ THANK YOU!!!
I couldn't agree more, reproducible and repeatable analysis is key to data analytics and one of the many reasons R rocks!! Thanks for your great content :)
I come from a computing background and have come to R after using programs like tableau. R is such a powerful tool from a programming perspective people need to know to use it from the start and NOT get dragged into expensive click n drag tools. The ability to use the same tool to create your reports as the one you used to get the findings is one of the strong points. The name R should be seen as meaning Reproducible so everyone can reproduce what you do so they can check your findings! (I am starting to teach it alongside Python next year at a UK uni).
To be clear, one great thing about SPSS is that you can write code, which captures all of the benefits of sharing and reproducibility you expressed, but you also have the option of a graphic user interface. If you use the latter, what you do gets written as code by the software, so you can still share and reproduce it. All of that said, I'm learning R, because it's open-source and in high-demand among potential employers. From all of the great things I've heard, I expect to be a true convert soon.
Thanks for the comment Olson. Good point. I hope you enjoy learning R. I'll be posting lots of videos (so hopefully we'll be on this journey together).
Great job! You are the best R video teacher I have found. Much appreciate you sharing your knowledge and experience with R with interested learners. Great work!
I came from a edX MOOC by Harvard X about R. I literally got bored watching the professor reading lines from his book by reading from a TelePrompter. It is not engaging at all. I said to myself that i might come to RUclips and see what other non-professor labeled people are teaching about r. The first video i watched was yours. Omg. You made me want to learn r passionately. You are not reading but telling with passion. You demonstrate directly from the workplace with ide and coding lines. You start with very easy examples so that learners can focus on the skill rather than understanding the task. Brilliant. And i should not forget the informal language that you use, which is much more engaging and easy to understand. And your humor, of course. Just love it.
i literally just came from edX to learn how to use R from RUclips same as you i felt the techniques used there as barely engaging. you must have finished your course by now though.
Day 1 of Learning R, I'm a fresh grad and hope to master R after watching all of your videos. Thank you for your dedication to teaching, I Hope to publish Great papers using R sooner through learning from you. God Bless you!
5 years old and found this channel - THANK YOU!! You made my life a lot easier, if you’re still answering questions - is there any other programming languages that I should be using along side R?
I love R. I see R as a friend who is always there to help me. R has its quirks and idiosyncracies, but if you are patient, it will solve your problems.
Very clear explanation, thank you! I have to learn R for a business analysis class this semester, and I was very intimidated by the thought of programming. It seems much more approachable after this.
Great sir, I was thinking R as something impossible to learn as I have nothing background in programming. But your first vedio filled confidence in me to atleast start learning. Many thanks to your channel it's really useful
Thanks for the video! I think the main reason behind people are using R is that it's free! However, I myself don't find easy way to write codes and commands. It's maybe because my background is not in statistics or in mathematics. So look forward to having more videos on how to make R more easy.
Clear, encouraging, motivating and perfectly paced. Plus, I can actually read what's on your screen (pay attention fellow r-tubers). Fantastic job, man. Subscribed.
I wish I had this when I was taking econometrics in the 1990's. R kicks so much ass. The data wrangling you can do with dplyr (and tidyverse in general) is mind blowing.
To be fair, I really don't see much added value of dplyr over SQL. Given that I pull my data from a DBMS, I prefer doing much of the wrangling using SQL before importing into R
I love how stata gives you a table with all the infos, but I wish they taught us econometrics with R. Not everyone had stata, so if you ask me how to use it, I didn't learn much. Didn't know there was an open source program...
It's exciting to watch your videos, I highly appreciate it. It's elementary to learn. I recently just started data analysis using R. I will follow all of your lectures.
Thank you so much. I was struggling with SPSS for over two weeks, and your this video was so convincing that I am trying to install R right away. I will catch up for your videos. I hope I will have a good time with R.
Watching this short video has saved me from making a very bad investment decision into purchasing an extremely expensive quantitative analysis tool for my Six Sigma project
Attending a seminar tomorrow on R coming from an SPSS background in medical research. I'm definitely scared of the programming aspect of it. Some of the analyses we're running are quite complex and the point and click system really do serve its purpose, especially in the older generation of scientists. Boiling down to it, R vs SPSS seems to be an upcoming UI battle such as the OS one with Windows vs Linux. One being more user friendly, and the other open source and more versatile
The more complex the analysis is, the more benefit you get from a program. It records and documents exactly what was done and makes the more complex and treacherous processes more reliable. Furthermore, suppose you spot a mistake in one step of a very long process. You can correct that mistake and rerun the entire program. If you try that with a point and click approach with very many steps, there is a great likelihood that one of your "click-steps" will be wrong. We are only human, but a computer running a program is not human. PS. I would be very surprised if there were no programming options for SPSS, SAS, etc. They all started as programmable languages on mainframe IBM computers before the introduction of PCs.
Thank you Dr Martin, though I have a little R language experience, unlike other videos yours is much fan and easy to understand and follow and your presentation made me eager to learn more about R. Hope to see more videos!
Is it THAT difficult? I’m torn between learning SAS or R, namely because I’m aiming for a public health career and it’s my understanding that SAS is used more in public health agencies...but R is becoming more popular across industries, so I’m stumped.
Greg you’re fantastic wish I discovered you earlier (before the grim costly tutorials I barely paid attention to) but here now and excited to learn again
Waw I was actually nervous to learn that I should go from SPSS to R to run some stats; but it might actually be good news from what I am hearing ! Love your enthusiasm !!
Well thank you for helping to get rid of this fear of programming. I've been a data person in NGO and charities but have always avoided R and any form of programming cos it seemed so complex. I will give it a try now.
Oh myy this is am maaaaazziiing...! thank you very much..! I had been exploring for the past weeks looking for " R for Dummies", most of those vids I'd encountered made me freak out even more.. (and got me thinking, should I try finding "R for super duper dummies" tutorial vid out there..) but your 101 R Explanation here is just like golden nail so precisely prick in my head... ( eh do I use the right word..?) again.. thank you.. from today I will follow your lesson here religiously... *Duan, in Devon, England
I like your enthusiasm! I would like to add however that you can use Stata for reproducible reporting and it isn't just point and click. It uses do files, which are programming scripts, like in R. The documentation is heaps better for Stata than for R. Both Stata and R run on C. Where R wins is the graphics options and the availability of cutting edge methods that are usually developed for R as it is free.
when you performed the correlation test (cor.test), does R check for if the data is normally distributed? therefore it knows when to use pearson or spearman correlation test depending on if the data is parametric or nonparametric?
Awesome.I've been trying programming languages.C#,PHP,C,C++,Rust and Ruby.I think C++ was the best of the lot but having watched your video I'm going to download R.My father who is the top actuary in the US is learning "R".He studies science and maths for fun.
Convinced and subscribed! Can't wait to be done with my residency exam and sink my teeth into something other than endless memorisation (not complaining tho).
My god you have no idea how much I love R. I don't used SPSS or SAS or any statistical programming except Pyton (can you even called Multi-purpose Language like this built for analysis?). The syntax is almost human like and there's so much packages out there that almost impossible to learn it all in one lifetime. What's more I freaking like %>% function. You can cleaning, analyze, and visualizing your data in one go! Shout out to the creator Ross Ihaka and Robert Gentleman and the community for creating packages that make our life as data scientist easier 😘🥰
R has proved to be quite scary for me. I started a program with a top 40 university here in the states, and there is absolutely no support. I need help. I am spending 30 - 40 hours a week looking for answers in stack overflow, and I'm lost, like a child wandering alone in a mall. I need so much help-- these are the best videos I've found.

Absolutely 100 % true
Absolutely love the way you explain. Learned from your short videos 10x more than in the class.....
Thank you.
This is great. I look forward to mastering R. One of the best skills I can gain as a public health practitioner.
I agree Mahommed - Mastering R is a great skill in the Public Health space. :)

Great to hear that Smoucan!! I have a few videos in the pipeline that you're going to LOVE. I must say, the more I learn about R the more I love it.
Great job! You are the best R video teacher I have found. Much appreciate you sharing your knowledge and experience with R with interested learners. Great work!
Wowwwww this made me feel way less nervous for my econometrics class this semester! Great video😁
Hey!👋🏼
I'm an Economics student too from CU and I'm still struggling with programming languages for Data Analysis and Econometrics 😐, can ya help??

He's just like "stay tuned" music kicks in all like a commercial is happening then suddenly phases back in to explain... Lol that transition.

Great to hear!
I wish you were my professor, you make it seem so easy, thank you!!

Very simple and easy! Great videos for R beginners!
Clarity in voice and explanation 👌🏻👌🏻
So much South Africa. Love it! I now know exactly what R is used for.
haha thanks
I think these teaching videos are useful and easy-understanding for fresh learners.
Thank you for your feedback, Antone. Much appreciated! 👍
Thanks a lot! I can't tell you how much helpful your videos are!

Marvelous video. Will be sure to get into R
Awesome video! Thanks for simplifying it.
Awesome video with extremely concise content! Thank you!
Brilliant one !! Clarifies many useful questions though its very short!!
Thanks for watching!
Loved the intro. Im subscribing and going to follow through ur guidance and training. Ill begin in a weeks times. Stay in touch. Tim
Convinced and subscribed! Can't wait to be done with my residency exam and sink my teeth into something other than endless memorisation (not complaining tho).
I fully enjoyed, and motivated to join R users community
That's great to hear, thanks!

You can watch mine too. The channel contains both Python and R playlist, with detailed source files downloadable.
Glad you liked it! Thanks!
This video is excellent, thank you for posting.
R has proved to be quite scary for me. I started a program with a top 40 university here in the states, and there is absolutely no support. I need help. I am spending 30 - 40 hours a week looking for answers in stack overflow, and I'm lost, like a child wandering alone in a mall. I need so much help-- these are the best videos I've found.
