rule-class {RGeostats} | R Documentation |
This class contains the definition of a set of facies in a bi-gaussian framework, i.e. by the minimum and maximum gaussian thresholds along each gaussian random function.
The Lithotype rule describes the way the Lithotype rules are defined. The bigaussian space is partitionned into rectangles: this subdivision is performed in sequential operations called 'nodes'. At each node, either a rectangle can be divided into two sub-rectangles, or one rectangle is assigned to a facies. A facies can be assigned to one and only one rectangle.
Objects can be created by calls of the form new("rule", ...)
