How to properly include dependencies in the DESCRIPTION file of R package?

Question

I am writing an R package and here:

R package does not load dependencies

An user indicates that (s)he changed

Imports: dplyr (>= 0.4.3), ggplot2 (>= 2.1.0), lazyeval (>= 0.1.10)

to

Depends: dplyr (>= 0.4.3), ggplot2 (>= 2.1.0), lazyeval (>= 0.1.10)

And the problem with required packages for a new R package was solved. However, that person did not indicate if the change was done manually or by coding. I am doing the change manually and my problem persists (and I really believe the problem is about importing packages or dependencies).

My questions are:

1- Is it just fine to edit the DESCRIPTION manually? If not, 2- Which is the proper way to do the change?

Very much thank you in advance

Answer 1

To answer your questions:

(1) It is fine to update the DESCRIPTION file manually.

(2) There is no "proper way" to do this, but I find that the best way to add an R-package as an import is to use usethis::use_package("package") . This will add it to the correct place in the DESCRIPTION file, and will remind you to reference the packages you use as package::function() (which is needed, as the Imports field only load, and don't attach, the packages).

Regarding putting a package in Depends vs. Imports : you should almost always put packages your code relies on as Imports . You can read more about it here .

I hope this was useful.
