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:
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
package ‘OpenMx’ is not available (for R version 3.0.0)
Any suggestion on what to do appreciated!
