I don't usually comment, but this man here is the best I've come across on youtube,. Damn, too good
@max5916
We really appreciate your best YouTube channel for learning R we looking forward to see more especially for survival analysis, parametric and non parametric tests
@johnrussell5715
I do love your enthusiasm Greg, it really keeps me interested in watching through to the end!
@harrisonnash4948
Life saver using this vidoe in a last min dash to finish some coursework
@nonoobott8602
Your tutorials are unarguably the most explicit and practical for the use of R. Beyond using R as a tool, you explain a lot of statistical concepts. Thanks for all you do, I've learned a lot from your channel
@domyndegeya7760
Thank you so much Dr Martin. As a beginner , the way you explain the R programming makes me loving that language more and easy to deal with coding. Keep up with more great videos.
@Shawn-gm4cf
Honestly love all your videos. Detailed explanation and yet simple and straightforward. Keep up the great work.
@JamesEllis-i4j
Incredible channel, the material is better than any course I have paid for. The delivery and the breakdown of topics into separate videos are perfect for learning. Thank you for sharing your expertise and time.
@antonreinhold8478
Thank you so much, you're such a huge help! I dont think i would pass my 'digital data analysis' course without your channel
@deniseortiz8567
Out of all the online classes and videos I have done, I WISH I STARTED WITH THIS ONE!! Thank you!
@Sorj108

You are an awesome teacher. I want to give you a hug right now! 😊Thank you for making it so easy to foloow through.
@KarstenDrKempf
Very helpful. the perfect mixture between the background ideas ( what data to dismiss) and the R way to do so. Hope to see more videos. Enjoy X-mas
@summer7361
You sir have an incredible voice for teaching. Glad I found your channel
@HiltonT69
Very clear, useful and interesting. I'm just getting into R and this helped me understand how it can be used for sensible data cleaning.
@danquixote6072
Very useful thank you - especially the section on NAs and recoding. Also appreciate the editing, effects, sound quality and close ups of the code. I’ve recently been using the star wars database for my English teaching lessons to help students with the interrogative. How tall is R2D2? How much does Darth Vader weigh? Etc. One request if possible - Times, Dates and TimeDates. Thank you again, your videos have been very helpful.
