degreesFreedom: Degrees of Freedom of a Covariance Matrix

In BenBarnard/covEstR: Estimators for Covariance Matrices

Description

Degrees of Freedom of a Covariance Matrix

Usage

degreesFreedom(x)

Arguments

x	a matrix with class covariance

Details

This function uses the f_eval function from the lazyeval package to return the degrees of freedom stored within the df attribute of a matrix object having the additional class covariance. This evaluation is necessary because the df attribute of a matrix with class covariance is stored as a formula object.

Value

The degrees of freedom of the covariance matrix, as a numeric object

Examples

degreesFreedom(cov(iris[,1:4]))
lapply(cov(iris, group = "Species"), degreesFreedom)
