If you mean the data you sent to Peter, it got scrubbed by the list
servers as well (they are somewhat draconian, but appropriately so in
the long run). The absolute best way to send R data via email (esp on
this list) is to use the dput() function which will create a plain
text representation of your data _exactly_ as R sees it. It's a little
hard for the untrained eye to parse (I can usually get about 90% of
what it all means but there's some stuff with rownames = NA I've never
looked into) but it's perfectly reproducible to a different R session.
Then us having the same data is a simple copy+paste away.

For more on dput() and reproducibility generally, see

It could be the floating point thing (it's hard to say without knowing
how your data was calculated), but Rui seems to think not.
