OpenMx Help

I am writing some functions that need to select some submatrices with variable indices. Let's consider the following sample code. The issue is that mxModel() only recognizes x in the gobal environment rather than inside a function. Have I missed something? Thanks.

myFun <- function() {
x <- 2
cat("Matrix in R:\n")
A1 <- matrix(1:16, ncol=4, nrow=4)
B1 <- A1[1:x,1:x, drop=FALSE]
print(B1)
myModel <- mxModel("test",
A2 <- mxMatrix("Full", nrow=4, ncol=4, values=1:16, name="A2"),

i tried to install openmx with

source('http://openmx.psyc.virginia.edu/getOpenMx.R')

but i get this errormessage on my r-terminal:

Hi all,
Fitting tri-variate models with CIs but CIs look odd.
They are to close to the point estimate and lower point is sometimes higher that point estimate.

Hi
I need to find out how to run openMx singlethreaded on a Linux system running R 2.15.1
It seems to be running multi-threaded by default and spawning a couple of hundred threads which is causing issues on our cluster which runs a condor queueing system.
thanks

Hi,

I've calculated genetic and environmental cross-trait correlations in a bivariate model, based on the correlational approach for scalar and non-scalar sex limitations (Neale et al., 2006, Twin Research and Human Genetics).

I've tested their significance by looking at the CIs and by checking what happens when I drop each parameter.

Now I have the situation where zero lies within the CIs - but when I drop the parameter, the model changes significantly. How is that possible (--> output attached!)?
(For a different phenotype, this didn't happen.)

Hi, I'm trying to install on a Fedora 17 system, it fails with:

checking for inst/npsol/linux/x86/gcc4.7/libnpsol.a... no
configure: error: npsol library not found

I've installed successfully on ubuntu 12.04 (which has gcc v 4.6).

Is would it work to copy over the library, or does this really need to be recompiled?

Sorry if this is a stupid question, but I have been having trouble getting to grips with OpenMx.

I have been using the sample script UnivariateTwinAnalysis_MatrixRawConACE.R. I would like to extend this in two ways:
* Print out a, c, and e (where appropriate) path variables and the standardized version of these for all models, (i.e. AE, CE, E not just ACE)
* Print out confidence intervals for ACE.A/ACE.V etc.

Can anybody help with this?

Thankyou

Karin
