Description

Example dataset

Format

A data frame with 43 rows and 13 variables:

Sample.ID: sediment sample ID
Sample.type: sediment sample type
Organism: organism abbreviation, HA = Hyalella azteca
Day: measurement day for toxicity endpoint (post-initiation)
Endpoint: toxicity endpoint
Hit: logical; whether we classified the sample as toxic (based on effect >25%)
Cd: cadmium concentration, mg/kg dry weight
Cu: copper concentration, mg/kg dry weight
Fe: iron concentration, mg/kg dry weight
Mn: manganese concentration, mg/kg dry weight
Ni: nickel concentration, mg/kg dry weight
Pb: lead concentration, mg/kg dry weight
Zn: zinc concentration, mg/kg dry weight

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.
