It has been, at least in a slightly different context. Sweave is not
very flexible when it comes to repetitive tasks: you cannot loop over
mixed R/LaTeX code. One way to work around is to define, in the
Preamble, a \newcommand containing most LaTeX code and calling it in
the R loop via a cat() statement. For a fully worked example see [1].

Unfortunately this is still very inflexible. I guess the "right"
answer to this is either 'brew' or 'markup' (or perhaps some other
packages out there), although I've never fully investigated the two
solutions since the workaround was good enough for my needs.
