Loading shinyBS at the launch of the app -- not the orthodox way

[mpascariu]

The {shinyBS::bsTooltip} is used within the UI of an app to add a tooltip to a Shiny input or output. However, for some reason is it not working unless i load it as library(shinyBS) within the run_app() function. This is not the nice way and during the R CMD checks we get the following warning:

checking dependencies in R code ... WARNING
  'library' or 'require' call not declared from: 'shinyBS'
  'library' or 'require' call to 'shinyBS' in package code.
    Please use :: or requireNamespace() instead.
    See section 'Suggested packages' in the 'Writing R Extensions' manual.

Tried that, and is not really working.
Is not a big deal since everything works nicely but yeah...
