...	Further arguments, currently not used

Examples

## Not run: 
data(bartlett2009.fitted)
derivatives.phenophases <- PhenoDeriv(
	x=bartlett2009.fitted$fit$predicted, fit=bartlett2009.fitted$fit
	)
plot(bartlett2009.fitted$fit$predicted)
abline(v=derivatives.phenophases[c(1:2,4)], col=palette())
mtext(names(derivatives.phenophases[c(1:2,4)]), 
	at=derivatives.phenophases[c(1:2,4)], 
	line=-2,
