getlambda: Object constructor for incidence matrix between the variables
Description
The function creates an object of class incidence that defines the partial order between the variables.
Usage
getlambda(...)
Arguments
...
The relations between the variables that define the structure of the poset, see details below.
Value
an object of class incidence.
Details
The relations are defined for couple of variables. They are defined by the names of the two variables and the symbols < and >. For instance, if the variable A is covered by the variable B, write the relation as A < B or B > A. If a variable is not comparable with the others, write the name of the variable without comparisons.
