getRecursiveCoeffs: Get final recursive harmonics model coefficients

In LobellLab/SCYMr:

Description

Runs a 2-term harmonic regression for the specified number of iterations. Modifies getHarmonicFits to return the coefficients instead of fitted values

Usage

getRecursiveCoeffs(ts, iterations, origin, dependent0, ...,
  dt_col = DATE, omega = 1)

Arguments

ts	Data.frame containing columns date, dependent variable, and any grouping variables.
iterations	Number of recursive harmonics to fit
origin	reference time; format should match df date column
...	additional grouping variables; unquoted
dt_col	unquoted column name for date column. Default is DATE
omega	default is 1
dependent	column name for dependent variable

Examples

# apply harmonics by pointID
library(dplyr)
library(lubridate)
library(stringr)
library(broom)

coefficients <- df_satelliteSeries %>%
  getRecursiveCoeffs(iterations = numIterations,
                     origin = ymd("2018-01-01"),
                     dependent = "GCVI",
                      omega = 1.5, pointID)
