Retrieve the class specification of an object

S7_class() returns a class specification for any R object, in a form that can be passed to method() or used in any S7 dispatch context.

• For S7 objects, the S7 class.

• For S3 objects, a new_S3_class() wrapping class(x).

• For S4 objects, the S4 class.

• For base types, the matching class_* (e.g. class_integer).

• For missing arguments, returns class_missing.

Any R object.

#> @ validator  : <NULL>
#> @ properties :

# Also works on non-S7 objects
S7_class(1L)
#> <S7_base_class>: <integer>
S7_class("x")
#> <S7_base_class>: <character>
S7_class(mean)
#> <S7_base_class>: <function>
S7_class(factor("a"))
#> <S7_S3_class>: S3<factor>
