Description Usage Arguments Value Author(s) See Also Examples

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

1	rsquare(x)

`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

The squared Pearson correlation coefficient as numeric value.

NDVI

	# 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]])
