Default scaffoldWidget shouldn't throw devtools::check() errors/warnings

[ColinFay]

Hey,

When build a default htmlwidget, the base elements throw devtools::check() errors.

Here is a reprex :

cd /tmp/
R -e "usethis::create_package('rrr');setwd('rrr');htmlwidgets::scaffoldWidget('rrr');devtools::document();devtools::check()"
[...] # output truncated

Erreur : R CMD check found ERRORs

I have to manually add {htmlwidgets} as a dep when it could be done automatically.

And still it throws documentation errors :

cd rrr

As far as I can tell, the license error is perfectly normal (you can't enforce the license) but HTML entry in doc + the non documentation of default parameter (which are htmlwidget specific so I'm not sure how to document them) could be prevented.
