Beamer needs to be told that a frame contains verbatim content, which is 
what Sweave uses for R input and output.  There are a few ways to do 
this; the one I use is to put this at the start of the frame:

\begin{frame}[containsverbatim]

You had the [t] option on the frame; I don't know beamer well enough to 
know if this is compatible with containsverbatim.
