Question

How to apply the "apply" function on a single column in r?

Answer 1

This post will show you how you can use the R apply() function, its variants such as mapply() and a few of apply()'s relatives, applied to different data structures. Of course, not all the variants can be discussed, but when possible, you will be introduced to the use of these functions in cooperation, via a couple of slightly more beefy examples.
