The data give growth measurements on Tammar wallabies (Macropus eugenii). Each line is a set of measurements on an animal at a particular time. Most lengths are in tenths of millimetres. The data from some animals is very fragmentary.
|Loca||Location of animal|
|Leng||Length of animal (tenths of a millimetre)|
|Pres||Pes (foot) length|
|Weight||Weight (tenths of a gram)|
|Age||Age in days from birth|
