gullweight {rpanel}

The weights of herring gulls captured at different times of year

Description

These data are part of a large sample collected by Prof. P. Monaghan of the University of Glasgow in a study of the weight changes in herring gulls throughout the year. Some birds were caught in June (coded as month 1) and others in December (month 2). Since weight is dependent on the size of the bird this information is recorded in the form of the head and bill length, hab (in mm), the distance from the back of the head to the tip of the bill.

The data are used in the rp.ancova example script.
