designLatinSqrSys {dae}

Generate a systematic plan for a Latin Square design

Description

Generates a systematic plan for a Latin Square design using the method of cycling the integers 1 to the number of treatments. The start of the cycle for each row, or the first column, can be specified as a vector of integers.

Usage

designLatinSqrSys(order, start = NULL)

Arguments

order

The number of treatments.

start

A numeric containing order unique values between one and order. These are interpreted as the value for the fist column for each row. If NULL, 1:order is used.

Value

A numeric containing order x order integers between 1 and order such that, when the numeric is considered as a square matrix of size order, each integer occurs once and only once in each row and column of the matrix.
