Details
h.trisate is a field-collected dataset containing sediment chemical concentrations for metals and toxicity classification data for
the amphipod Hyalella azteca. Data are from freshwater sites in Kansas, Missouri, and Oklahoma (Ingersoll et al 2008). The Hit variable was
assigned by the authors of this package.
