I've begun work on modifying the myOmxGraphviz functions so that it picks up on the values and places them onto relevant paths (with some other todo and suggestion stuff in there also. For instance, if variables have paths coming in and out already, residual paths should move out of there way. If a manifest has an outgoing path, the residual should try and get onto the north side. one-arrow lines should be straight (not sure if graphviz knows about that).

anyhow, the working functions are here

trunk/models/failing/addValue.R
if you paste them into R you can use

The issue creator insists on having a version number when issues are created. However, no versions are available in the pulldown list - have to choose ' ' (blank) over 'none' to get it to work.

It seems that constants cannot be used in the arguments to mxConstraint function calls. Good news, only the first and third arguments need be fixed! Here is an example snippet:

> onelocus<-mxModel("onelocus", mxAlgebraObjective("NegativeLogLikelihood"),

mxMatrix("Full", nrow=1, ncol=1, free=TRUE, values=c(.3333), name="P"), # P, freq of allele 1
mxMatrix("Full", nrow=1, ncol=1, free=TRUE, values=c(.3333), name="Q"), # Q, freq of allele 2
mxMatrix("Full", nrow=1, ncol=1, free=TRUE, values=c(.3333), name="R"), # R, freq of allele 3

There seems to be a bug in mxModel when remove=T
example code
library(OpenMx)
thisOMxModel <- mxModel("testModel", mxMatrix(name="Afac", type="Full",nrow=8,ncol=5))
testit <- mxModel(thisOMxModel, mxMatrix(name="Afac", type="Full",nrow=8,ncol=5), remove=T)
# Error in as.character.default() :
# no method for coercing this S4 class to a vector

The Mx script attached works ok. The parser generates a lot of errors. It is possible that my installation of the parser is the problem, as it has never yet worked for me.

At the end of svn up, which was working fine up to this point, I got:

Latest version of R breaks install of OpenMx on Windows platform at least.

I ran the code below and got a crash. replicated twice
I think it is because the dataset in the model doesn't match the manifests list (salthouse vs demoOneFactor), but shouldn't crash....

require(OpenMx)
salthouse <- read.table("http://www.subjectpool.com/data/2009/andrea/salthouse.txt", header=TRUE, sep="\t", as.is=c(TRUE))
manifests <- names(salthouse)
latents <- c("G")
factorModel <- mxModel("One Factor", type="RAM",
manifestVars = manifests,
latentVars = latents,
mxPath(from=latents, to=manifests),
mxPath(from=manifests, arrows=2),

Based on the discussion from the last developer's meeting. It sounds like we will not be installing trac on the new webserver. Which is fine by me. Except a web interface to subversion commit history has been extremely helpful as a developer to browse other people's commmits. This seems like a good alternative: http://www.websvn.info/. Any thoughts?
