We ask that use the following two citations in your publications that use OpenMx. As of OpenMx 1.2.1, these citations are available from R by invoking
Steven M. Boker, Michael C. Neale, Hermine H. Maes, Michael J. Wilde, Michael Spiegel, Timothy R. Brick, Jeffrey Spies, Ryne Estabrook, Sarah Kenny, Timothy C. Bates, Paras Mehta, and John Fox. (2011) OpenMx: An Open Source Extended Structural Equation Modeling Framework. Psychometrika. Steven M. Boker, Michael C. Neale, Hermine H. Maes, Michael J. Wilde, Michael Spiegel, Timothy R. Brick, Ryne Estabrook, Timothy C. Bates, Paras Mehta, Timo von Oertzen, Ross J. Gore, Michael D. Hunter, Daniel C. Hackett, Julian Karch and Andreas Brandmaier. (2012) OpenMx 1.2 User Guide.
The journal citation is for the OpenMx anchor paper. It serves as an introduction to OpenMx and helps track the usage of the software package in scholarly publications. The User Guide citation communicates which version of OpenMx you are using in your analysis and the author list of the User Guide reflects the nature of the development group that changes over time.
If you download a new version of the package, or compile a new from from the svn, you should quit R and restart to ensure you have the new version loaded
Download the appropriate binary package.
Save it in your USB drive
nb: In Windows, the disk drive is represented by either e:/ or e:\ in R.
You can view the list of demo files with this command:
Then this will show you where they are on your system
system.file("demo", "BivariateSaturated_PathCov.R", package="OpenMx")  "/Users/~/Library/R/2.9/library/OpenMx/demo/BivariateSaturated_PathCov.R"
(you need to add ".R" to the displayed name that demo() reveals)
A named entity is the term used by the OpenMx library for any S4 object that includes the slot "name". Examples of S4 classes in the OpenMx library that create named entities include MxModel, MxMatrix, MxAlgebra, MxObjectiveFunction, and MxData. An equivalent answer to this question would be any S4 object 'foo' such that 'foo@name' will return a value.
If model refers to a MxModel object, then use "?summary(model)" or the more generic "method ? summary('MxModel')". Documentation for the summary function was added in version 0.2.5.
Yes, there is. You can install it using Getbundles
Unfortunately, currently you must install the 32-bit OpenMx binary on a 64-bit windows machine. This is because we don't have a copy of 64-bit NPSOL library compiled for windows. We are working on getting this issue resolved and will provide a Windows 64-bit installation of OpenMx when possible.
There is a known bug with OpenMP and OS X 10.7. You can install a more recent version of gcc on your machine, this should replace the default runtime with a more stable library. A more recent gcc version is available from hpc.sourceforge.net or macports. Another alternative is to install the sequential OpenMP binary.
