rbind Missing Something: Need New Eyes
...one else will probably see what needs to be added to the statements.
The data frame has this structure (without any data):
$ PHYLUM : chr
$ SUBPHYLUM : chr
$ SUPERCLASS : chr

One command (all on one line) is:
itis.ttable <- rbind(itis.ttable, data.frame(PHYLUM = "ARTHROPODA",

I'm currently stumped on how to interpret/compute odds ratios for two and three way interactions
