Is an object a linkdat object?
is.linkdat(x) is.singleton(x) is.linkdat.list(x)
x |
Any |
Note that the singleton class inherits from linkdat, so if
x is a singleton, is.linkdat(x) returns TRUE.
For is.linkdat: TRUE if x is a linkdat (or singleton)
object, and FALSE otherwise.
For is.singleton: TRUE if x is
a singleton object, and FALSE otherwise.
For is.linkdat.list: TRUE
if x is a list of linkdat/singleton objects.
