Description

Phenology extraction in Derivative method (DER)

Usage

PhenoDeriv(x, t, ...)

## S3 method for class 'fFIT'
PhenoDeriv(x, t = NULL, analytical = FALSE, smoothed.spline = FALSE, ...)

## Default S3 method:
PhenoDeriv(x, t, der1, IsPlot = TRUE, show.legend = TRUE, ...)

Arguments

x	numeric vector, or fFIT object returned by curvefit().
t	doy vector, corresponding doy of vegetation index.
...	Other parameters will be ignored.
analytical	If true, numDeriv package grad and hess will be used; if false, D1 and D2 will be used.
smoothed.spline	Whether apply smooth.spline first?
der1	the first order difference
IsPlot	whether to plot?
show.legend	whether show figure lelend?
