I really appreciate the animation. Kept the lecture a lot more engaging and clear when you were reviewing the code

Wonderful video!!! I can't recommend it enough! I'm an SPSS user, but I'm learning R programming to be able to run analysis anywhere I go for free (and on the run lol), and then to be able to help others with their own data analysis when they don't have SPSS. R is becoming a more universal package in my opinion. Thank you so much Greg Martin for all your efforts and dedication to teaching global minds :) keep it up!

I've watched all 16 videos. Thank you very much for so much time to explain it all, Greg! Lots of thanks from Brazil! Dabadum!

This is a complete semester course described in detail in an hour. My Professor, who is paid to teach this course, will be unable to cover even half of what is shown in this video until the semester is through. When I raise inquiries about specific codes in class, the Professor becomes enraged. Greg, I can't thank you enough for this video and so many others. R programming is quickly becoming second nature to me. How can I get access to the linear model and other graphs you used to demonstrate some aspects of the programming? Thank you very much. You are simply the best!

This channel has been so helpful to learn and continually reference. Thank you!!

Total gratitude!, even some statistics theoretical aspects are much more clear for me now.

Great video. Thank you so much for your quick and accessible introduction to programming in R. 10/10

Wonderful job explaining this, I thank you so much for putting this video out here for free! I learned and re-learned so much of these that I previously were not able to understand in class!

Excellent video! Have been trying to practice with this video, getting the 'starwars' data is not in the r sample data. Can anyone tell me how to get that 'starwars' data so that I can practice symultaneously?

Excellent Explanations overall..my deepest thanks to you

Great explanation. Thanks Greg

Thank you for this chef-d’œuvre

I’ve followed all the steps but can’t view filtered starwars plot.. getting all kinds of errors about not finding %>% function

I felt like I had eaten 3 plates 5 minutes before I started work. That's why I watched it at 0.5 speed for the 2nd time. Sorry for this. I wish it had been 3 hours and it was explained slowly. But thank you for your work. I will close this gap with your other videos..

This video is genuinely stellar. Is there a way we can download the R Script you used in this video?

Amazing video. Quick question. When going over the summarise code at the 30:00 mark. Can you also use the mutate function to add those columns because that seems to be what is happening within the summarise function. Or is that innapropriate or considered "bad code"? Thanks. Love the content

Most of the packages don't load even though I typed everything exactly as you did

where is the documentation for all this?

For those who cannot see the starwars data set: if (!require(dplyr)) install.packages("dplyr") library(dplyr) starwarsDF

No words can express my deep gratitude. Thank you so much, Mr. Greg. Please, keep up the great work.

I cannot tell you how excited I am that I finally understand what I am doing in R! Granted, I've spent about 8 hours working through this 1 hour video, but it has finally "clicked." Thank you!

love this video so much but the dataset ''starwars'' is not available to me, I'm not sure why and I've tried adding it seperately but that hasn't worked so far, does anyone know a solution to this? It would really help since it's easier to follow along when it's the same dataset

I was searching for videos on R programming and stumbled upon your channel. The way you explain the concepts is so wonderful. Simple and precise. I like the fact that in many of your videos, you do touch upon topics that were taught in a previous video. This video is like a refresher just before one is about to give his / her exam. Thank u so much for putting in the hard yards and making life for us wannabe data analysts slightly better. Wish u the best in life!!!

as albert Einstein once said “If you can't explain it to a six-year-old, then you don't understand it yourself” . you are the best.

R Programming 101, amazing content I really liked it

Thanks a mill for this, Greg! I've watched the video 4 times and worked through all of it in RStudio. Not only did I learn a lot of R, I also did grasp some concepts in statistics that I've struggled with before. There's a big difference in the level of understanding when trying it out on your own. Awesome! I highly recommend putting in the time, it was so worth it. I've now downloaded the visualization cheat sheet as well, but that I think I'll have to save until the next weekend ;) Hope your weekend was just as great.

okay I was following along, mucking around at the starwars bit. I did a height/mass variable, arranged by new density/fatness variable. and apparently lukes Uncle Owen Lars is the densest or fattest human being in star wars. in fact, at only 5'10 (178cm) he apparently weighs 120kg (260lbs). Look up his actor, there's absolutely no way that dude weighs 260lbs at that height. so I did ?starwars and the data comes from starwarsapi, who absolutely refuse to list on their website or anywhere else where they pulled this data (their arse I believe.) googling around, joel edgertons weight is around 180lbs. Just about 70% of the character owen lars weight. so I think owen lars may in fact not be a carbon based lifeform. he's denser than darth vader!!!! he's only slightly less dense than General Grievous and some other robot guy.

Thank you so much Greg for sharing your hard-earned knowledge with the rest of us. You are doing a wonderful job; it is clear that it takes time and passion to make these informative, well-structured videos and for that I am greatly thankful. Wish you all the best :)

Ehm, the starwars dataset is not in my version of RStudio, which should be the latest version (installed yesterday). This makes it hard to follow the instructions. When I write View(starwars) I get this response "Error in View : object 'starwars' not found" ??

Hey Greg I do not have the starwars dataset for some reason. Do you know why or how or where I could get the dataset?

Amazing video! Thanks for this. The only explanation I found missing in the video is that you need to code library(package_name) for the packages each time you open up Rstudio in order to use the package again.

I've watched four tutorials on R programming and yours is the best one! Not only concise, quick and relevant, but the way you talk about these topics is truly entertaining and captivating :) Thank you

Just what I needed. What a brilliant video! Can only agree with the top comments. I have programmed many languages, and found you made it both entertaining and I think you covered everything I wanted to know to get an introduction - you make it look easy peasy lemon squeezy - By the way, you didn't mention your name ;D just thinking that would be helpful, as maybe you are doing a conference sometime, then I would definetly want to see you present.

Greg, I absolutely love your teaching style. I was flip-flopping between R and Python and you have convinced me that for data exploration, graphing and statistical analysis, R is the best bet. No doubt I will still learn Python but your style of teaching is what has got me convinced and serious about learning R. I can't thank you enough.

I have learned so much, so much here! Concise, clean, and amazing tutorial. Thank you so much!

This video is definitely a life saver! I watched it twice before my midterm exam, and went from barely knowing how to import a csv file and do basic work with it to getting a 90 in my midterm! This even video even helped me get the statistics base knowledge needed to properly understand and analyze the data that is provided by the codes in the video. Again, this is a lifesaver for everyone trying to understand statistics and basic RStudio coding! Forever grateful for all your help!

Hello, First of all ty very much for your informative video. The goin was very smooth form e at the beginning. However while trying to "plot()" the data of the the pipe operator I came across the following error: Error in xy.coords(x, y, xlabel, ylabel, log) : argument "x" is missing, with no default Normally I wouldn't have bothered you, and I tried checking the error @ online forums however me being an absolute novice in r and programming in general, couldn't get much help. would really be grateful if you'd help me out w/d this.

I agree with your approach of using in-house data for these demonstrations 100%. I can't count the number times I have started a lesson (and even paid for it) and quit in frustration because I could not access or find the data they used. Some instructors use some "obscure" data from a R package but don't bother telling you it came from. Others use "external" data that is either no longer accessible (or needs a signup or API) or in has been "wrangled" from the original form into some other shape. Many times I have had to reverse engineer or simulate the data on my own. If you are trying to teach some specific task or topic then this misses the point of the lesson (reminds of my high school when our math books were in Swedish - not my native language - I and I was busy trying to figure out what the words meant rather than doing the math) . So thanks for be so good about using built-in data rather than some obscure data!

Coming soon... a video from 2 hours boom chacalaka ;)

Thank you so much! I looked through a lot of tutorial videos but found them slow, boring and confusing. But you are awesome teacher! 👌

names str(friends) Error in str(friends) : object 'friends' not found

I'm really attracted now, as a Biochemist and have found myself needing R knowledge, your video gave me hope, Sir. Remain blessed 🙏

What is better for bioinformatics and system biology? Python or R?

It was the "boom shakalaka" and "easy peasy lemon squeezy" that let me know I was in the right place. So much better than any boring University course teaching less and not as well. Thank you!

I’ve been learning python for the last few months and haven’t used R in a long time… this is the perfect refresher I needed for an upcoming interview I have! Excellent stuff :-)

Do you feel this is the programming language to learn as an aspiring Epidemiologist completing their MPH Epidemiology degree program? Thanks Greg!

Hi Greg, thank you so much for creating this channel on R programming. Just subscribed. I am amazed to find you have already created so many videos already. You ROCK!!

I'm very slow with this. I opened RStudio, but only the R Console window appears. None of the other sections you describe in the beginning are there though... what am I doing wrong, please?

hey, great video! just wanted to ask- missing

I have already installed R and R studio on my Windows 10 operating system, which is my host operating system. I also have Linux in my virtual box. Should I have install R and R studio again in Linux virtual machine?

The content is just wonderful. Much appreciated. I am studying environmental management and have no bg in programming. However, I always heard of R. With the help of your video, I learnt a lot of things. Cheers

Thanks for the video. I got what I needed for work. I have to translate some R code into Python to run in Airflow for work. 😁 I think I understand the basics. I need to learn more about character stripping, substrings, and character replacing in R now. I have a script that replaces a certain number of spaces with one comma. Pretty simple.

I cannot thank you enough. This has been such a huge help. I will be sharing this with the rest of the students in my Data Science unit and in the university Discord for future students. Absolutely brilliant teacher.

Thank you so much for all this détails

Can we get the R script file, please? (P.S. Amazing video & loved the sound effects!)

Great video thanks. BTW: "startwars" is part of the library(dplyr), not tidyverse

How did you draw the graphs in the statistical analysis section? Starting from t-test all the way to linear model. Using the code I only saw outputs in the console.

thank you very much for this. I followed step by step but mine keep saying :object "height" not found. please help. I have serached the whole universe .

the word I love you doesn't currently express how grateful I am. This is super helpful!!! Thank youuu!!

Hey i loved this video and because of this amazing video i might learn something new. So i wanted to how to do the setup for rstudio? Meaning is it free and if so do i need to put some setting or click some options while downloading or just default. I wanna get started on r and practice so i need to know

omg I have been watching TONS of tutorials to no avail. I wish I'd found you weeks ago!

Am immensely grateful. I am going into this and will come back to say how am doing. Thank you

Hi, I live in Australia and am desperate for a statistics tutor. Is there anyone on your team who would be interestested in being paid for tutoring me on R as well as meta analysis? Kind Regards

Thank you so much for this course, very efficient and easy to understand!

really good rhythm ...Definetely will share with my fellow dum colleagues!! Really usefull

teacher how can I upload another set that is not included in "tidyverse". Thank you so much for this helpful course

Thank you so much for this rich yet concise introduction of R for data analysis. I found it so informative and beginner-friendly.

why pivot_longer does not work , also the console wrotecould not find function "%>%"

all tutorials use the built in data sets. so how in t he world do you input data efficiently then? lol

Can anyone please tell me how to install gapminder pacakage? I cannot find it in my default library....

Sorry might be a silly starter question, why my r doesn't run like your click. I can only highlighted it to running.

Can you teach us how to apply all of these for manipulating excel sheets including data instead of datasets you showed us here?

Wow, very quick and efficient way of learning how this program works! Learned so much while following this course, have subscribed and looking forward to more videos created by you. Thank you!

Does anyone know if there is a keyboard shortcut for the "%in%" command - first appears @32:05

loving the occasional 'boom shaka laka' hahaha, very entertaining and informative. thank you

drop_na(column_name) is given as error. What should I do?

Hi Greg! thanks a lot for the nice explanation. I encounter an issue in the min. 44:00. When trying to plot the t-test, I get "Error: object 't_test_plot' not found". How could I solve this issue?

Johnson Carol Rodriguez Mary Hall Matthew

I was just getting started to jump into my Statistical Programming Course but I hate going into things blind. This was an EXCELLENT resource i was intimidated by R programming. This video honestly gave me a huge boost in confidence. Thank you.

This has been really helpful for me in my current job. Thanks you 👍 ... Any chance you could do Plotly and Markdown HTMLs in an hour long episode? ❤😅

Question, I wasn't able to install Starwars in my R Studio. It said it wasn't available on my version of R. I have a MacBook Pro with a mac OS version of R. Does anyone have any solutions?

Hernandez Sharon Williams Ruth Anderson Patricia

The next time, I would like to access the starwars file for example and doing the tasks at the same time

Walker Robert Davis Christopher Young Karen

Alright, I'm stuck, Please help. I'm so tired. > library(tidyverse) Error: package or namespace load failed for ‘tidyverse’ in loadNamespace(i, c(lib.loc, .libPaths()), versionCheck = vI[[i]]): there is no package called ‘colorspace’

this. saved.my.bRain. thank you!!!!!!!!!!!!!!!!!!!!!

HEY-O WHAT CONSOLE TYPE ARE YOU USING BIG BROTHER? I DON"T HAVE QUITE THE SAME AESTHETICS AS YOU DO?

Merci beaucoup pour la vidéo. I'm experienced in SAS and Power BI, but did not know where to start on how to program in R. Your video touched upon all the important themes we need to know to get started.

Could you share the script for practice

no not possible lemon easy peasy? instead of that please tell the shortcuts and etc. please watch the mosh hamedanies courses , thanks by

How to create a variable store a list of Stored (read.csv) like : localPAth="c:/..." list_of_DataFrame= list() List_name=c("dasd.csv","adsdasd.csv") for(name in List_name){ append(list_of_DataFrame, read.csv(paste(localPAth,name,name , sep="" )) }

day-ta not dar-ta ... I had to switch off, it was driving me mad.

I'm just getting started on this video and it's great! One oddity, my installation of R doesn't seem to have the starwars data. Any body else have this issue?

Everything worked up to plot(). I get "Error in plot.default() : argument "x" is missing, with no default"

My Google Coursera could never 😂

Smith Nancy Taylor Melissa Walker Cynthia

Thank you so much for this. It was REALLY helpful!

You are Amazing! Thank you. It took me 6 hours because I stop the video and practice.. But, I learned the basics of R in even 58 minutes. Keep it up
