S7 wrappers for base types

The following S7 classes represent base types allowing them to be used within S7:

• class_logical

• class_integer

• class_double

• class_complex

• class_character

• class_raw

• class_list

• class_expression

• class_name

• class_call

• class_function

• class_environment (can only be used for properties)

We also include three union types to model numerics, atomics, and vectors respectively:

• class_numeric is a union of class_integer and class_double.

• class_atomic is a union of class_logical, class_numeric, class_complex, class_character, and class_raw.

• class_vector is a union of class_atomic, class_list, and class_expression.

• class_language is a union of class_name and class_call.

Value

S7 classes wrapping around common base types and S3 classes.

Examples

class_integer
#> <S7_base_class>: <integer>
class_numeric
#> <S7_union>: <integer> or <double>
class_factor
#> <S7_S3_class>: S3<factor>
