My SAS brain was still plugged in. I had a missing data point entered as a
"." I didn't think anything of it since SAS treats that as missing data.
Apparently it confuses R. I deleted the "." re-imported the data and
everything was beautiful. If anyone is bored I am still interested in why R
orders lattice plots from bottom to top.
Thanks,
Phillip
