Below is a very simple Sweave file that produces two tables the first has no caption and the second has a caption (if you want to see it http://www.zevross.com/temp/test.pdf).

Hi,

If you compare the output of the two commands, the 'floating = TRUE' variant places the tabular environment within a table environment. The tabular environment does not support the \caption command, table does, hence no caption if the tabular is not contained within a float (floating = FALSE).
