In RETURN-project/BenchmarkRecovery: Benchmark recovery indicators derived from remote sensing time series

Description

Convert time series to annual frequency: The toAnnualTS function converts a time series with n observations per year to an annual time series (one observation per year). The main concept is to select observations per year closest to a given day of year that have no missing value (NA). Here, the day of year for which the seasonality is maximum is being used.

Usage

toAnnualTS(tsseas, tsi, obspyr, dtmax = 1/12)

Arguments

tsseas	vector of observations (time series) representing the seasonal component of the time series to be converted
tsi	vector of observations (time series) that needs to be converted to an annual time series
obspyr	number of observations per year of the time series to be converted
dtmax	maximum time (expressed in year, so 1/12 equals one month) between selected observation and the seasonal maximum

Value

vector of observations (time series) with annual observation frequency
