This S4 class inherits from the S3 class
The environment serves as a container to hold the data, poset and the
poset related functions of a probabilistic index model generated
by the function
pim. The objects of this class
behave much like an environment, but contain some extra slots
with information on the objects inside the environment.
an environment of class
pim.poset containing the poset-related functions
(normally these are
environment has the object itself as parent.
a character vector containing the names of the vectors that represent the data
integer value indicating the number of observations in the environment
a _named_ list containing the classes of the
objects inside the environment. Note that the value should be the one
a logical value indicating whether or not the poset was added before.
This class is not exported, so it can't be extended as for now.
Although it is possible to use the function
creation of new instances, users are strongly advised to use
new.pim.env in case they need to manually
create a new instance of the class
