I would think knitr package would be useful in this endeavor. And possibly RStudio....
If that doesn't do it, someone here may have a better hint, but solving this kind of question can require studying both the input (R code) and output (tikz/LaTeX code). While the R code belongs here, details of the rest get OT pretty quick.
