Is selecting and 'C-c C-r'-ing the 3 chunks separately that bad? The pieces for what you want are there. You can use Stangle() on a Sweave format file to extract the R code chunks. In your usage, a crude implementation would involve writing your selection to a file, running Stangle on it, and source()-ing the resulting .R file. Others may have better suggestions.
