Where do you use the group_by function?

group_by is used when you want to group your dataset by a specific column.

Go to R studio and try the following commands.

View(mtcars) # this command will give you an overview of the mtcars dataset. You will notice that the first column(mpg) is not organized.

Now try using,

group_by(mtcars,mpg)  # You will notice that all similar values have been grouped together.
