faq-error-incompatible-attributes

This error occurs when <code>vec_ptype2()</code> or <code>vec_cast()</code> are supplied
vectors of the same classes with different attributes. In this
case, vctrs doesn't know how to combine the inputs.
To fix this error, the maintainer of the class should implement
self-to-self coercion methods for <code>vec_ptype2()</code> and <code>vec_cast()</code>.

Defines new notions of prototype and size that are used to
provide tools for consistent and well-founded type-coercion and
size-recycling, and are in turn connected to ideas of type- and
size-stability useful for analysing function interfaces.
