When a user installs a package using SystemRequirements: and they donβt have an installed program / package yet, will R install it?
The clipr package is a great example of this question: https://github.com/mdlincoln/clipr/blob/master/DESCRIPTION . If a package declares SystemRequirements: in a DESCRIPTION file, will it be installed R to check?
