pcAlgo-class {pcalg}R Documentation

Class "pcAlgo"

Description

The object contains the results of a call of the function pcAlgo.

Objects from the Class

Objects can be created by calls of the form new("pcAlgo", ...) or by a call of the function pcAlgo.

Slots

graph:
Object of class "graph" which contains the undirected graph that was estimated
call:
Object of class "call" which contains the original call
n:
Object of class "integer"; number of samples that were used to estimate the graph
max.ord:
Object of class "integer"; maximum size of neighbourhood set that was conditioned on during the algorithm
n.edgetests:
Object of class "numeric"; number of edge tests that were performed
sepset:
Object of class "list"; the conditioning sets that made an edge drop out during the run of the algorithm
zMin:
Object of class "matrix"; contains at entry ij the minimum z-Value of all conditional independence tests of edge ij

Methods

plot
signature(x = "pcAlgo"): Plot the resulting undirected graph; if argument "zvalue.lwd" is true, the linewidth of the edges reflects the minimum absolut z-Value that was computed during all tests for the particular edge, i.e., thicker lines show more reliable dependencies; the argument "lwd.max" controls the maximal linewidth.
show
signature(object = "pcAlgo"): Show properties of the fitted object
summary
signature(object = "pcAlgo"): Show details of the fitted object
