Mirex concentration, weight, capture year, and species of Lake Ontario salmon.
Mirex concentration, weight, capture year, and species of Lake Ontario Coho and Chinook salmon.
A data frame with 122 observations on the following 4 variables.
a numeric vector of capture years
a numeric vector of salmon weights (kg)
a numeric vector of mirex concentration in the salmon tissue (mg/kg)
a factor with levels chinook and coho
The year variable should be converted to a factor as shown in the example.
