averissimo
commented
7 months ago Note that this is an issue with R6 classes only.
For this issue to go forward we need to decide if we can accept not having examples on the method description (see different options on screenshot below)
- Keep as is without any protection against
Suggestpackages being installed - Use
@examplesIf, but have it being omitted from method definition (JSONArchiver$writein the example below) - Surround example by an if statement
