## Initial Question
 

From my understanding, there are three general ways to replace "library" statements in R packages:
1. List all packages on which our package relies in the "Imports" section of the DESCRIPTION file, and use the "@imports" statement in the NAMESPACE file to attach these packages to R.
2. List all packages on which our package relies in the "Imports" section of the DESCRIPTION file, and use package::function in our R code whenever we want to call a function from another package. For example, if we wanted to use the mutate() function from dplyr, we would write: dplyr::mutate().
3. List all packages on which our package relies in the "Depends" section of the DESCRIPTION file.

## Answer
I combo option 1 and 2 and heavily suggest not using option 3:
