Calculates the r-square value of a model.

Usage

result.rsquare(values, type="cod")

Arguments

values	A list containing the modelled (doy.model) and the observed (doy.observed) values.
type	The value of type (either ‘cod’ or ‘pearson’) determines whether the coefficient of determination or the squared pearson correlation coefficient is calculated.
