[R-pkg-devel] Package from non-mainstream repository

When checking my package with R-devel, I get the following notes.? In 
the current and earlier versions of R, I got the same note concerning 
incoming feasibility, but the NOTE about the package not being available 
for checking did not occur.? What do I need to do to get rid of that note?

* checking CRAN incoming feasibility ... NOTE
Maintainer: 'Barbara Lerner <blerner at mtholyoke.edu>'

Suggests or Enhances not in mainstream repositories:
   rdt
Availability using Additional_repositories specification:
   rdt   yes   https://end-to-end-provenance.github.io/drat/
* checking package namespace information ... OK
* checking package dependencies ... NOTE
Package suggested but not available for checking: 'rdt'

Thanks for your help!
