I am building a Shiny application based on an unpublished package. I have, therefore, explicitly created stand-alone functions of parts of this unpublished package. Shiny call these functions when needed. On my local machine, Shiny is not calling this unpublished package. I have even uninstalled this package to make sure that Shiny is independently functioning.
Yet, when I deploy this package to shinyapps.io, I face an error about this unpublished package is required.
I suspected that an earlier Shiny deployment of this app might have interfered and that this dependencies is an echo. So I removed that earlier version to make sure that this app is not interfering with the new app. But the same problem persists.
In summary, a package dependency should not be required, yet Shinyapps asks for it.Any idea of what is going on?
Not sure how to write a reproducible example of this particular issue.
