Rhizoctonia root rot infections

Description

Rhizoctonia root rot infections.

Usage

data(rhizoctonia)

Format

A data frame with 100 rows and 5 variables.

Details

A dataset containing the number of infected roots and the sample coordinate. The data were collected by Dr Jim Cook at Washington State University.

• Xcoord Longitude of the sampling location.

• Ycoord Latitude of the sampling location.

• Total Total number of roots sampled at that location.

• Infected Number of infected roots found at that location.

• Yield Barley yield at that location. These data were obtained by hand-harvesting a 4-square-meter area in the sampling location. One observation is missing.

Note

We acknowledge Hao Zhang for providing these data.
