I'm pretty sure it's the loading of the citrus package that is causing the error and have added the Additional_repositories field with a link the package on Github, but still haven't been able to resolve the issue. There are very specific installation instructions for the package <https://github.com/nolanlab/citrus/wiki/Installing-Citrus>, which may be contributing to issues.

I don't think you posted your DESCRIPTION file, but the likely problem 
based on the check log is that your "Additional_repositories" field 
points to something that CRAN doesn't recognize as an R package repository.

Probably the easiest way to create the right structure is to use the 
drat package; see  https://github.com/eddelbuettel/drat  for instructions.
