These data are from from McDonald (2009), by way of Mangiafico (2015), on
the relationship between the ambient temperature and the rate of cricket
chirps per minute. Data were collected for two species of the genus Oecanthus: O. exclamationis
and O. niveus. The data are contained in a data frame called crickets with
a total of 31 data points.
