Fit harmonic trend model to time-series values

Description

This is a wrapper function around harmonic from the TSA package that constructs harmonic functions for fitting a harmonic trend model.

Usage

vectorHarmonics(
  x,
  frq = 12L,
  st = c(1982, 1),
  nd = c(1986, 12),
  m = 2L,
  fun = stats::median
)

Arguments

x	Numeric. A vector containing time-series values.
frq	Integer, defaults to 12 (months). The number of observations per unit of time. See ts.
st	Numeric. A vector containing start year and month.
nd	Numeric. A vector containing end year and month.
m	Integer, defaults to 2. The number of pairs of harmonic functions to be created. See harmonic.
fun	Aggregating function to be applied to the fitted values.

Value

A numeric vector.
