Measurements on a sample of Manduca Sexta caterpillars

A data frame with 267 observations on the following 18 variables.

`Instar`	Coded from 1 (smallest) to 5 (largest) indicating stage of the caterpillar's life
`ActiveFeeding`	Indicator (`Y` or `N`) of whether or not the animal is actively feeding
`Fgp`	Indicator (`Y` or `N`) of whether or not the animal is in a free growth period
`Mgp`	Indicator (`Y` or `N`) of whether or not the animal is in a maximum growth period
`Mass`	Body mass (in grams)
`LogMass`	Log (base 10) of body mass
`Intake`	Wet food intake (in grams/day)
`LogIntake`	Log (base 10) of Intake
`WetFrass`	Amount of frass (solid waste) produced (in grams/day)
`LogWetFrass`	Log (base 10) of WetFrass
`DryFrass`	Amount of frass, after drying, produced (in grams/day)
`LogDryFrass`	Log (base 10) of DryFrass
`Cassim`	CO2 assimilation (ingestion - excretion)
`LogCassim`	Log (base 10) of Cassim
`Nfrass`	Nitrogen in frass
`LogNfrass`	Log (base 10) of Nfrass
`Nassim`	Nitrogen assimilation (ingestion - excretion)
`LogNassim`	Log (base 10) of Nassim

Student and faculty researchers at Kenyon College conducted numerous experiments with Manduca Sexta caterpillars to study biological growth.
