[R-pkg-devel] Acknowledging small functions from another package

[David Hugh-Jones]

Hi,

One of my packages copy-pasted some small functions (stuff like `%||%` for
is.null) from ggplot2. (Both packages are MIT-licensed.)

What is an appropriate way to acknowledge this in the DESCRIPTION Author:
or Authors using R section? (Note that the list of ggplot2 authors is long and
changing.)

Cheers,
David
