bean {pairwiseCI}R Documentation

Yield of beans in a two factorial field trial

Description

Block design with four blocks. Within the blocks a 2x3 factorial design was randomized: Two types of horse beans (Vicia faba) were grown under three fertilization levels of phosphor.

Usage

data(bean)

Format

A data frame with 24 observations on the following 4 variables.

block
a numeric vector
T
a factor with levels, describing the plant type, where T1 = short, and T2 = tall
P
a factor with levels, the phosphorus rate with levels P0 = 0, P25 = 25 kg/ha P50 = 50 kg/ha
yield
a numeric vector, giving the mean yields of beans in kg/ha
