This function scans LISREL (Joreskog & Sorbom, 1996) output for model matrices and fit indices.
Usage
readLisrel(x)
Arguments
x
String indicating the location of a LISREL output file.
Details
LisrelToR uses the following names for the model matrices:
LY
Lambda-Y matrix.
PS
Psi matrix.
BE
Beta matrix.
TE
Theta-Epsilon matrix.
TY
Tau-Y matrix.
AL
Alpha matrix.
LX
Lambda-X matrix.
PH
Phi matrix.
GA
Gamma matrix.
TD
Theta-Delta matrix.
TX
Tau-X matrix.
KA
Kappa
ObsCovs
The observed covariance matrix, or a list of such matrices for each group.
ImpCovs
The implied covariance matrix, or a list of such matrices for each group.
Furthermore, lisrelToR uses the following names for matrix types:
est
Parameter estimates
se
Standard errors
t
t-values
parSpec
Parameter numbers
Value
A list of class "lisrel" contaning:
fitIndices
Fit indices, currently not supported.
matrices
A list contaning the model matrices. For each group this list conains a list with for each matrix (using LISREL style naming, see details) a list contaning elements est for parameter estimates, se for standard errors, t for t-values and parSpec for parameter numbers. Use lisrelMatrix to extract the matrices.
variables
Currently not used.
Covariances
A list with elements implied and observed containing the implied and observed covariance matrices.

Examples
## Measurment invariance example:
download.file("http://sachaepskamp.com/files/mi1.OUT",modFile <- tempfile(fileext=".OUT"))
Lis <- readLisrel(modFile)
# Extract Lambda-Y for group 2:
lisrelMatrix(Lis,"LY", group = 2)
# Structure of object:
str(Lis)
# Print full LISREL output to console:
print(Lis)
