hai_fourier_discrete_augment | R Documentation |
Takes a numeric vector(s) or date and will return a tibble of one of the following:
"sin"
"cos"
"sincos"
c("sin","cos","sincos") When either of these values falls below zero, then zero else one
hai_fourier_discrete_augment(
.data,
.value,
.period,
.order,
.names = "auto",
.scale_type = c("sin", "cos", "sincos")
)
.data |
The data being passed that will be augmented by the function. |
.value |
This is passed |
.period |
The number of observations that complete a cycle |
.order |
The fourier term order |
.names |
The default is "auto" |
.scale_type |
A character of one of the following: "sin","cos", or sincos" All can be passed by setting the param equal to c("sin","cos","sincos") |
Takes a numeric vector or a date and will return a vector of one of the following:
"sin"
"cos"
"sincos"
c("sin","cos","sincos")
This function is intended to be used on its own in order to add columns to a tibble.
