In the NAMESPACE file it looks like you are importing from the 'viridis' package, which again imports 'ggplot', though I am not sure which function you are actually importing as importFrom("viridis", "viridis") does not match any function that I can see is exported by the package. Maybe you are unintentionally invoking a part of ggplot through viridis?
