Documentation

I was looking at this example:

http://openmx.psyc.virginia.edu/docs/OpenMx/2.6.7/_static/demo/OneFactorJoint_PathRaw.R

When I ran it, there were no estimates for the factor loadings.

This code doesn't include "facLoads". Shouldn't it?

oneFactorJointModel <- mxModel("Common Factor Model Path Specification", type="RAM",
manifestVars=c("x1","x2","x3","z1","z2","z3"), latentVars="F1",
dataRaw, resVars, latVar, means, thresholds)

I think this is what is needed:

When looking at a script, or script snippet, I find it very helpful to see syntax highlighting. I am an addict of highlighting. However, it is difficult to get demo scripts, or script snippets highlighted. One possible solution might be this:

http://alexgorbatchev.com/SyntaxHighlighter/

which currently lacks R support (and its wish list forum has been closed due to spam) but it is customizable. Possibly, building an R highlighter - and particularly one that understands OpenMx functions - would be useful? Or perhaps someone has another solution?

I tried to run the script given in:

http://openmx.psyc.virginia.edu/docs/OpenMx/latest/FIML_RowObjective.html

It seems to fail with the following error:

Running FIML BivCor
Error: Unknown reference 'filteredDataRow' detected in the entity 'secondHalfCalc' in model 'FIML BivCor'

am i doing something wrong? i merely copy pasted it.

Thanks for implementing the analysis of ordinal data in OpenMx 1.1. After running the code, it seems that there are some errors in the example.

Original S matrix:
mxMatrix(
type="Symm",
nrow=4,
ncol=4,
values=c(1,0,0,0,0,0,0,
0,1,0,0,0,0,0,
0,0,1,0,0,0,0,
0,0,0,1,0,0,0,
0,0,0,0,1,0,0,
0,0,0,0,0,1,0,
0,0,0,0,0,0,1),
free=c(T, F, F, F,

Hi
It would be very helpful to add a comment to the mxConstraint documentation to tell users that using this will turn off the standard errors.
I couldn't find any comments in the example ordinal data scripts advising users about this.
thanks

hi there,
I was expecting help(package="OpenMx") to startDynamicHelp.

Would be nice if it did, as the plain text is not very helpful :-)

The goal of this forum post is to "document" the list of mx* and omx* functions that were missing documentation.

These are based on v1648 as of 05/19/2011.

Undocumented mx* functions:
mxDeparse

Undocumented omx* functions:
omxCheckMatrices
omxCheckNamespace
omxExponential
omxGetRAMDepth
omxInterval
omxNameAnonymousParameters
omxParallelCI
omxQuotes
omxRAMtoML
omxSelectCols
omxSelectRows
