sincos: Trigonometric variables
In tfarima: Transfer Function and ARIMA Models
sincos R Documentation
Trigonometric variables
Description
'sincos()' creates a full set of seasonal trigonometric regressors
(cos/sin harmonics) for a seasonal frequency.
Usage
sincos(Y, n.ahead = 0, constant = FALSE)
Arguments
Y
A seasonal 'ts' object.
n.ahead
Integer. Extra observations to extend the sample.
constant
Logical. If 'TRUE', include an intercept column.
Value
A 'ts' matrix with trigonometric variables (and intercept if requested).
Examples
X <- sincos(AirPassengers, constant = TRUE)
