Line by tester example: eight lines crossed with three testers

Simulated yields of the 24 crosses of eight lines with three testers in a randomized complete block experiment with three replicates, drawn from a model with line, tester and line by tester effects. The data illustrate LineTester.

Usage

data(LineTesterData)

Format

A data.frame with 72 rows and 4 columns:

Line: line (factor, L1 to L8).
Tester: tester (factor, T1 to T3).
Rep: replicate (factor, 1 to 3).
Yield: yield (numeric).

Source

Simulated; the script is data-raw/LineTesterNC.R of the package sources.
