Function Argument Validation

Tools for validation and safe casting and recycling.

abort_if_not() abort_if()

Ensure the truth of R expressions

cast_if_not()

Cast objects to a given type

recycle_if_not()

enforce()

Ensure the truth of R expressions and cast/recycle objects.

schema() enforce_schema() add_to_schema()

Ensure the truth of data-masked R expressions and cast/recycle named elements.
