Leaf Boundary Data of Seven Species of Neocinnamomum

Description

The data consist of the leaf boundary data of seven species of Neocinnamomum.

Usage

data(Neocinnamomum)

Details

In the data set, there are four columns of variables: Code, LatinName, x, and y. Code saves the codes of individual leaves; LatinName saves the Latin names of the seven species of Neocinnamomum; x saves the x coordinates of the leaf boundary in the Cartesian coordinate system (cm); and y saves the y coordinates of the leaf boundary in the Cartesian coordinate system (cm).
