Overview

An object of this class represents a special R environment ("ENVSXP") that is at the base of the environment enclosure hierarchy, which has no "parent.env" and into which nothing can be assigned.

You shouldn't create instances of this class, it exists mainly to handle deserialization of "emptyenv()" by the "IO" classes.

Methods

"Statistics::R::REXP::EmptyEnvironment" inherits from Statistics::R::REXP::Environment, with the added restriction that it doesn't have attributes, enclosure, or any contents. Trying to create an EmptyEnvironment instance that doesn't follow this restriction will raise an exception.

Bugs and limitations

Classes in the "REXP" hierarchy are intended to be immutable. Please do not try to change their value or attributes.

There are no known bugs in this module. Please see Statistics::R::IO for bug reporting.

Support

See Statistics::R::IO for support and contact information.
