It may be a bit early for an extra package with OpenMx still being so actively developed, but I wonder if a public package might be a convenient place to bundle beta/test/hack/mildly useful functions together? This is really a question for the community as I strongly dislike the idea of adding to the developers workload (unless of course it involves cool new OpenMx features....then I'm all for working them round the clock ;).
For example, Ryne has a function on the forums for standardizing estimates, another thread has a way to get modification indices, another one has fit indices. I find myself regularly sourcing some of these files in, which works, but
Would people be interested in a sort of 'community sandbox' package where anyone could write, add, edit, functions for use with OpenMx? Would OpenMxers be willing to put (and update) their hacks, etc. in a public package if I set it up and maintained it?
If there's interest, I would probably use github or google code. Both are pretty good at allowing social coding so multiple people can contribute, edit, and comment and one can easily link to specific .R files so they could be referenced on this forum easily. github has the advantage that Hadley has even written the devtools package which allows one to install straight from github, google code has the advantage that I'm still using subversion and not terribly eager of switching to git ;) The purpose would just be to collect the code fragments from this forum and that may be hiding away on users systems that are too specific/buggy to be officially released anywhere but are still useful for what they do.
Just thinking out loud, maybe a lousy idea.
