fciAlgo-class: Class "fciAlgo" of FCI Algorithm Results

Description

This class of objects is returned by functions fci(), rfci(), fciPlus, and dag2pag and represent the estimated PAG (and sometimes properties of the algorithm). Objects of this class have methods for the functions plot, show and summary.

Usage

# S4 method for fciAlgo
show(object)
# S3 method for fciAlgo
print(x, amat = FALSE, zero.print = ".", ...)
# S4 method for fciAlgo
summary(object, amat = TRUE, zero.print = ".", ...)
# S4 method for fciAlgo,ANY
plot(x, y, main = NULL, ...)

Slots

The slots call, n, max.ord, n.edgetests, sepset, and pMax are inherited from class "gAlgo", see there.

In addition, "fciAlgo" has slots

amat:

adjacency matrix; for the coding of the adjacency matrix see amatType

allPdsep

a list: the ith entry of this list contains Possible D-SEP of node number i.

n.edgetestsPDSEP

the number of new conditional independence tests (i.e., tests that were not done in the first part of the algorithm) that were performed while checking subsets of Possible D-SEP.

max.ordPDSEP

an integer: the maximum size of the conditioning sets used in the new conditional independence that were performed when checking subsets of Possible D-SEP.

Extends

Class "gAlgo".

Arguments

x, object

a "fciAlgo" object.

amat

logical indicating if the adjacency matrix should be shown (printed) as well.

zero.print

string for printing 0 (‘zero’) entries in the adjacency matrix.

y

(generic plot() argument; unused).

main

main title, not yet supported.

...

optional further arguments (passed from and to methods).

Methods

plot

signature(x = "fciAlgo"): Plot the resulting graph

show

signature(object = "fciAlgo"): Show basic properties of the fitted object

summary

signature(object = "fciAlgo"): Show details of the fitted object

Examples

## look at slots of the class
showClass("fciAlgo")

## Also look at the extensive examples in ?fci , ?fciPlus, etc !

if (FALSE) {
## Suppose, fciObj is an object of class fciAlgo
## access slots by using the @ symbol
fciObj@amat   ## adjacency matrix
fciObj@sepset ## separation sets

## use show, summary and plot method
fciObj ## same as  show(fciObj)
show(fciObj)
summary(fciObj)
plot(fciObj)
}
