OpenMx 0.3.3

This is a bugfix release for the OpenMx binary. Several bugs were affecting the confidence interval calculations. Please upgrade to this version of the OpenMx library. You should read the announcement for 0.3.2 if you have not already done so.

Release 0.3.3-1264 (May 24, 2010)

  • confidence interval frontend was requesting nonexistent matrices
  • omxNewMatrixFromMxMatrix() assumed input was always integer vector S-expression
  • confidence intervals mislabeling free parameter names

Release 0.3.2-1263 (May 22, 2010)

  • added 'newlabels' argument to omxSetParameters() function
  • now throwing errors to the user when detected from the backend in mxRun()
  • checkpointing mechanism implemented - mxRun(model, checkpoint = TRUE)
  • never computing confidence intervals for matrix cells where free = FALSE (all
    bets are off on algebras)
  • added mxOption(model, "CI Max Iterations", value)
  • added documentation for mxRestore() function
  • default expected means vectors are no longer generated


When I try to get OpenMx from the RGui, I get the following message:
Warning: unable to access index for repository
Warning message:
In getDependencies(pkgs, dependencies, available, lib) :
package ‘OpenMx’ is not available

Not sure what the problem is, please advise...


We haven't build a binary version of OpenMx for 64-bit windows. Once the R folks get a normal cross-platform toolchain working, that will be much easier. Until then, we are looking for volunteers with 64-bit windows who want to install all the compilation dependencies and build a copy. In the meantime, use the 32-bit version of R. If you need a 64-bit address space, we have linux builds available.
