object 
an object of class 
output 
a character string that must partially match one of:

not used, but allows methods for inheriting objects to have additional arguments. 
a numeric matrix of the variance represented by the factor model, or the systematic or specific variance portion of the model.
This has two additional attributes:
number.of.factors 
the number of factors used in the model. 
timestamp 
the date and time at which the model was originally created.
