OpenMx Help

Is it possible to get Open MX on Windows 8? When I enter:
"source('http://openmx.psyc.virginia.edu/getOpenMx.R')" I keep getting the following error message:

Warning in install.packages(pkgs = c("OpenMx"), repos = repos) :

Hi Everyone,

I ran into this problem today while doing a new installation of OpenMx, and I was just curious if this looked familiar to anyone: "/nfs/home/pascal/R/x86_64-redhat-linux-gnu-library/2.15/OpenMx/libs/OpenMx.so: undefined symbol: _gfortran_copy_string"

Thanks!

Hello.
We are currently developing an environment in R which would allow us analysing data without physical sharing of them, i.e. data (from one or several sources) are located on external server(-s) and R commands are sent to that server via a secured authenticated network. Only restricted summary statistics would be sent back to the analysis computer without disclosing any data. I will not go into details here, but just to give an idea of what it is.

Dear OpenMx experts,

I'm now working on a twin dataset with zygosity diagnosis is not exact, i.e. I only have one variable indicating the probability of one twin pair being MZ or DZ. In Mx we can "specify" this variable and "weight" it when estimating the covariance matrix. Dr. Neale has discussed this issue and provided the Mx script file here:
ftp://ftp.vcu.edu/pub/mx/examples/zygosity

The key commands are below:

G2: All twin pairs
Data NInput_vars=3 Nmodel=2
Labels t1 t2 pmz
Rectangular File=sim1.mz
Select t1 t2 pmz ;
Definition pmz ;

Matrices= Group 1
P Full 1 1

I just upgraded to R 3.0 on my Windows 7 PC. I am now trying to reinstall OpenMx. I get the following error message:

> source('http://openmx.psyc.virginia.edu/getOpenMx.R')
Warning: unable to access index for repository http://openmx.psyc.virginia.edu/packages/bin/windows/contrib/3.0

package ‘OpenMx’ is available as a source package but not as a binary

Warning message:
package ‘OpenMx’ is not available (for R version 3.0.0)

Any suggestion on what to do appreciated!

Hi everybody,

I have been trying to run a model when checking the assumptions. It is a univariate analysis with an ordinal variable with two thresholds, and I have two covariates.

Everything seems to be fine, but I get this error message:

> baseFit <- mxRun( baseModel, intervals=FALSE )
Running base
Error: In model 'base' the thresholds in column 'BFEED12th_01' of matrix/algebra 'fMZ.expThreshfMZ' contain NA values. Only the first 2 elements of this column are inspected.

Do you know what may be happening?
