Version 2.0.1 now available

Version 2.0.1 of OpenMx has been released. As usual, it can be downloaded by entering source('https://openmx.ssri.psu.edu/getOpenMx.R') into the R prompt. This patch provides several bug-fixes and small improvements:

  • Improved functionality of mxRefModels().
  • Confidence intervals can again be run with multithreading.
  • omxGetParameters() will now omit duplicated parameters, even when there are no submodels.
  • It is now possible to "condense" the 'labels', 'free', 'lbound', and 'ubound' slots of MxMatrix objects if they contain all NA or all FALSE, as the case may be. This is done with a new argument to mxMatrix(), condenseSlots, which presently defaults to FALSE. Condensing slots is intended to save memory, and is user-transparent as long as the $ accessor is used to access the slots.
  • This version introduces a useful new function, mxCheckIdentification(), which verifies whether a given MxModel object is locally identified.
