environment-class: Class "environment"
Description
 A formal class for R environments.Objects from the Class
Objects can be created by calls of the form new("environment", ...).
The arguments in ..., if any, should be named and will be assigned to
the newly created environment.Methods
    - coerce
 signature(from = "ANY", to = "environment"):
      calls as.environment.   - initialize
 signature(object = "environment"):
      Implements the assignments in the new environment.  Note that the
      object argument is ignored; a new environment is
      always created, since environments are not protected by copying.
