Environmental Variance and Covariance

Description

Computation of environment variance and covariance matrix.

Usage

traitstats.envcov(Treatment, Replication, DataFile)

Arguments

Treatment	Treatment column in the DataFile
Replication	Replication column in the DataFile
DataFile	Input Data file name

Details

Environmental variance and covariance matrix is computed as per the methodology given by Al-Jibour et al., (1958).

Value

Environment variance and co-variance matrix. Diagonal value indicating the environmental variance and upper and lower half of the matrix indicating the environmental covariance.
