lisrelMatrix {lisrelToR}

Extract LISREL matrices from lisrel object.

Description

This function can be used to extract matrices from the output of readLisrel.

Usage

lisrelMatrix(object, matrix, group = 1, type = "est")

Arguments

object

A "lisrel" object obtained by readLisrel.

matrix

Specification of the matrix to be extracted. See details.

group

An integer specifying which group the matrix should be extracted from.

type

Specification of the type of matrix to be extracted.

Details

LisrelToR uses the following names for the model matrices:

Examples

## Measurment invariance example:
modFile <- system.file("extdata", "mi1.OUT", package = "lisrelToR")
Lis <- readLisrel(modFile)

# Extract Lambda-Y for group 2:
lisrelMatrix(Lis,"LY", group = 2)
