richard your voice is so calm and clean also the teaching techniques everything made the video very cool.
Hi, does anyone know what I should do if the left sign in my file changes from "<" to "+" and thus doesn't run what I enter?
OBRIGADA AMIGA!!
your code is more like c
I would like to join the chorus for more videos by Richard; You explain these concepts in a masterful fashion. Yet ... keeping it simple <- Encore!
Much better example rather than other youtube teacher ❤
Does Richard ever narrate these videos?
Thank you so so much for this simple explanation. Many videos are just too complicated but this is just what I needed.
Thank you
Thanks
Great video! I am curious about using dplyr contains function to select columns that do not contain certain letter sin the string. I was hoping your video would cover how to filter out columns using the contains function. thank-you

You are Greatttttttttttttt. You have made my evening with this well-explained and straightforward application of aggregate function.
How to sum of all prices in column price when against cut is same in cut column in diamonds dataset in R programming
I wish this person would start uploading videos on R again, the simplicity of the explanations in these videos can't be beat. It is so easy to follow along.
Waooo what an explanation 🙂❣️
Print for each of the numbers x = 2, . . . , 20, all numbers that divide x (all factors) excluding 1 and x. For example, for 18, it should print 2 3 6 9
Thanks

Thank you so much!!!!!!!!!!
This is exactly what I was looking for a great example and explanation...subscribed for it!!!
Hello there, code only works in the console but does not work in script
Can someone please explain the results of the for loop at 5:42? What is the "-3rd" element of the vector Storage2? Why is the 4th element also a 9 in the results when the 4th element was never assigned?
THANKS M8 i have been watch 8 videos this helped!
