The following error is produced when attempting to call install.packages. Here
is the results of the traceback:
source('http://openmx.psyc.virginia.edu/getOpenMx.R')
Error in f(res) : invalid subscript type 'list'

5: .install.winbinary(pkgs = pkgs, lib = lib, contriburl = contriburl,
method = method, available = available, destdir = destdir,
dependencies = dependencies, ...)
4: install.packages(pkgs = c("OpenMx"), repos = repos)

I've tracked the error down to somewhere in available.packages defined in
src\library\utils\R\packages.R. I am guessing that the error in version 2.10
has something to do with the change: "available.packages() gains a 'filters'
argument for specifying the filtering operations performed on the packages found
in the repositories."
I can reproduce this, and yes, it is happening in one of the filters.
I'd guess it happens because your repository has only one entry (a
missed "drop=FALSE" somewhere maybe) or because the filter is finding no
matches. I'll track down the details and fix it.
Thanks for the report.
