Statistics::R::REXP::EmptyEnvironment - the empty R environment ("emptyenv()")

version 1.0002

    use Statistics::R::REXP::EmptyEnvironment
    
    my $env = Statistics::R::REXP::EmptyEnvironment->new;
    print $env->name;

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.

"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.

ACCESSORS

Just as in R, the name of the EmptyEnvironment is "R_EmptyEnv".

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.

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