R help - Dec 2023 - Advice on starting to analyze smokestack emissions?

Bert, Tim, Karl and Richard, thank you all for your suggestions and
help.

I will try the R-sig-ecology list.

Karl, I wasn't aware of the RAQSAPI package, but it looked promising.
However, when I went to the source of the data it uses, the United
States Environmental Protection Agency?s (US EPA) Air Quality System
(AQS) Data Mart database, it looks like interactive access to the data
is restricted to those who can document a professional agency
affiliation. I don't have that. I'll work with the package to see if
this is true regarding obtaining the data through it. Thanks for the
suggestion.

Richard, the Canada study of crematoriums was very useful. Thanks.

Thanks, again, all, for your help.
