Greetings and Salutations Marius,

For implementation help with “Additional_repositories”, which lacks a bit of documentation, please see: 

Under this approach, I am able use `imudata` package [https://github.com/smac-group/imudata] to build the vignettes within the `gmwm` package [https://github.com/smac-group/gmwm] with the suggests field filled in as: “Suggests: imudata”. Otherwise, CRAN would not accept the `gmwm` package as-is. 

(Regarding the package size claim, there really are not that many packages greater than 5 mb… For some figures on this, see: http://thecoatlessprofessor.com/programming/size-and-limitations-of-packages-on-cran/ )
