Description

Calculates the squared Pearson correlation coefficient of corrected and modelled timeserie.

Usage

rsquare(x)

Arguments

x

An object of class ‘NDVI’ containing corrected and modelled values. If corrected timeserie is not available, the raw one out of ‘values’ will be used

Value

Examples

	# load data
	data(avhrr)

	# create NDVI object, correct and model values
	ndvi.list <- modelNDVI(ndvi.values=avhrr.ndvi/10000, 
			year.int=1995, correction="bise", method="Growth", MARGIN=2, 
			doParallel=FALSE, slidingperiod=40)

	#plot
	plot(ndvi.list[[1]])

	# squared Pearson correlation coefficient
	rsquare(ndvi.list[[1]])
