Awesome, informative. It is a life saver. You are in my big 5 list of the finest R tutors. You could have spoiled us a little bit with the ungroup argument.

Wish I found this video 2 days ago; it solved 2 days’ worth of coding issues for me in the first 2 and a half minutes 😊 Thanks so much!

This is so helpful! I was stumped on the use of this in my project and this cleared everything up. Thank you so much!

Thanks so much for explaining this, especially how R actually calculates. It makes so much more sense now. I can that if you use the group by function and summarize with mean, then the numbers are actually different than without the group by function. This is because the latter is summarizing by all data and not just one group. :) cool

I was trying to think about this for a while! This is a great and intuitive explanation!

You're just amazing!!! Very clear explanation, thank youuuuu!! SUBSCRIBED!

I played this video at 1.25 speed and didn't get it. Then I played it at 0.75 speed and bamm, I understood what you said.

Dear Ben, suppose you have a fourth columns with year when the test was taken by each indyvidual suppose 2017,2018,2019. How would you get the score and aggregate at the same time. My question is how to convert a single column with variables ( years) into as many columns as years ( 2017,2018,2019. : rows group by name Jen, Sarah, Ben......and columns are named 2017,2018,2019. It is feasable somehow ? Will be obliged for help. Thank you

Hello, I am having a issue with the group_by function still. If I have 4 variables/columns .. say ( a b c d ) can I use the group by to only view column b and c?

you can use select and then group_by bro

Ben, you need to score more. Nice video, help me a lot.

how did you create the data?

this video should replace the R dplyr course on datacamp

I wish u could reply my question, knowing this video is 5 years old. my question: how did you create the table directly on the input pane of the console. I am trying to create the table the traditional way by mentioning my variables. I input the variable "name" but found some names appear more than once

is there a way to have a column saying how many rows of data are in each group?

summarize(n=n(), etc...) at the end of the pipeline should work

good content terrible microphone
