ffsuitable

Test ff object for suitability

ffsuitable tests whether FF_RETURN is an ff object like FF_PROTO and having attributes FF_ATTR.

ffsuitable(FF_RETURN, FF_PROTO = NULL, FF_ATTR = list()
, strict.dimorder = TRUE, fail = "warning")
ffsuitable_attribs(x)

`x`	an object from which to extract attributes for comparison
`FF_RETURN`	the object to be tested for suitability
`FF_PROTO`	the prototype object which `FF_RETURN` should match
`FF_ATTR`	a list of additional attributes dominating those from `FF_PROTO`
`strict.dimorder`	if TRUE ffsuitability requires that the dimorders are standard (ascending)
`fail`	name of a function to be called if not ffsuitable (default `warning`)

TRUE if FF_RETURN object is suitable, FALSE otherwise
