[R] sweave tables as images?

[baptiste auguie]

My guess is that it would be impossible to use the table size in
Sweave, only mildly non-trivial in knitr with a proper hook. The
easiest hack in either of them would be to manually open the png
device, and use cat() with \includegraphics{} where you want the plot
diplayed.

HTH,
