veilleux | R Documentation |
A data frame consisting of bivariate time series from an experiment for studying prey-predator dynamics. The first time series consists of the numbers of prey individuals (Didinium natsutum) per ml measured every twelve hours over a period of 35 days; the second time series consists of the corresponding number of predators (Paramecium aurelia) per ml.
