| PhenopixMY {greenbrown} | R Documentation |
This function takes a multi-year time series and applies curve fitting and phenology extraction functions based on the greenProcess function in the phenopix package. The function returns an object of class PhenopixMY (phenopix multi-year) which contains a list of phenopix objects. PhenopixMY can be plotted using plot.PhenopixMY.
