[R] Help with importing scripts within the same package?

[Jeff Newmiller]

You keep talking about "including" and "sourcing" and now "dependencies". Stop that. Don't do it, don't think that. All functions in all R files of a package are loaded together in one namespace. Your separation of functions between R files in the package source is entirely for your editing convenience. Dependencies only apply between packages, not within them.
