Package `SFBA` not available

When I run R CMD check I get:
> Package suggested but not available for checking: ‘SFBA’

Typically when I get this error it meas that the package is on github but not on the server.

Start by running R CMD check and locating where the package declares SFBA as a suggested dependency. Determine why SFBA is unavailable from the checking environment; done means the package check no longer reports this unavailable suggestion, with the dependency declaration or availability issue resolved.
