Wheat Kernels

Description

Data.frame

Usage

data(wheat)

Format

The data frame has 275 rows and 7 variables:

class

hrw = hard red winter wheat and srw = soft red winter wheat.

density

Density of a kernel.

hardness

Hardness of a kernel.

size

Size of a kernel.

weight

Weight of a kernel.

moisture

Moisture content of a kernel.

type

Kernel's condition: Healthy, Sprout (sprouted prematurely), or Scab (infected with a fungus).

Details

A study on kernels of wheat was done. There are two classes of wheat: hard and soft red winter wheat. Each kernel measured for density, hardness, size, weight, and moisture content. Each kernel was classified by visual inspection if healthy, sprouted, or scab. A row in the data frame represents a kernel of wheat.
