Rsq: Multiple R-squared

In soilphysics: Soil Physical Analysis

Description

Function to calculate the multiple R-squared and the adjusted R-squared from a fitted model via lm or aov, i.e., linear models. For a model fitted via nls, nonlinear models, the pseudo R-squared is returned.

Usage

 Rsq(model) 

Arguments

model

a model fitted via lm, aov or nls.

Value

A list of

R.squared	the multiple R-squared (for linear models) or the Pseudo R-squared (for nonlinear models).
adj.R.squared	the adjusted R-squared.
