endfloat package is re-ordering my subsections

[Christopher W. Ryan]

Using TexLive on Windows. I'd like to use endfloat. The latex source
file is generated by Sweave from R.  Here is a MWE, modified from the
Sweave-created one.  If you toggle using the endfloat package, hopefully
you will see my problematic results.

Any suggestions?

Thanks.
