[R] Advice on starting to analyze smokestack emissions?

That depends on how exactly everything must match your primary question. The ecology group might be helpful for how biodiversity changes with proximity to a smokestack. They might have a better idea if the smokestack was from a coal fired powerplant or oil refinery. The modeling process would be similar, though the abundance of individual contaminants would be quite different. Just my thought for what it is worth.

You might also try the R-Sig-ecology list, though I would agree that it's not clearly related. Still, air pollution effects...?
