assert_engine

Function that returns a logical value (possibly
a vector).

predicate

Passed to the <code>predicate</code> function.

The error message, in the event of failure.

Either 'all' or 'any', to reduce vectorised tests to a
single value.

what

A logical value.  If <code>FALSE</code>, <code>NA</code> values
cause an error; otherwise they do not.  Like <code>na.rm</code> in many
stats package functions, except that the position of the failing
values does not change.

na_ignore

The workhorse of the package.  If a condition isn't met, then an error
is thrown.  This function is exported for use by package developers so
that they can create their own assert functions.

A minimal set of predicates and assertions used by the assertive
    package.  This is mainly for use by other package developers who want to
    include run-time testing features in their own packages.  End-users will
    usually want to use assertive directly.
