Data on maximal running speed and body mass in terrestrial mammals

Description

In an investigation of the relationship between mass (kg) and maximal running speed (km/hr) in terrestrial mammals, Garland (1983) collected information from published articles on these two variables for a large number of different species. The measurements are not all recorded to the same level of accuracy since the results have been collated from the work of a number of different scientists.

The mammal_speed dataframe consists of four columns of data:

• Name: the name of the mammal;

• Family: the family of the mammal;

• Mass: the characteristic mass of the mammal in kg;

• Speed: the characteristic maximal running speed of the mammal in km/hr.

The rodent dataset in the rpanel package is a subset of these data.
