Thanks to Yihui and Bela for responses to my question...Yihui's example pointed me toward a simple solution...I should have responded to the list to get the solution out there, but only responded to Yihui...This was my response:
"Aha! I see the trick now! You have the xtable Swaeve chunk in an ERT box within the float. I had the chunk in the float alone...it worked fine with the caption below, but when I put the chunk below the caption, it printed as tex...now in an ERT box it works fine! Thank you again, Yihui." -- Shane
