step_fft_transfer_experimental — step_fft_transfer

Calculates the transfer function with pgram results.

Usage

step_fft_transfer_experimental(
  .rec,
  terms,
  spans = 3,
  detrend = TRUE,
  demean = TRUE,
  taper = 0.1,
  n_groups = 200,
  time_step = 1,
  formula = NULL,
  role = "augment",
  ...
)

Arguments

.rec: the R6 recipe object.
terms: the unquoted names of the variables to use or a selector function. terms replaces the `...` of the recipes package but requires variables to be included within `c()`. For example to include variables x and y you would write `c(x,y)` in the hydrorecipes package.
spans: vector of odd integers giving the widths of modified Daniell smoothers to be used to smooth the periodogram.
detrend: logical. If TRUE, remove a linear trend from the series. This will also remove the mean.
demean: logical. If TRUE, subtract the mean of the series.
taper: specifies the proportion of data to taper. A split cosine bell taper is applied to this proportion of the data at the beginning and end of the series.
n_groups: number of results
time_step: numeric monitoring interval size
formula: formula notation to specify inputs and outputs
role: character - the name of the role
...: additional arguments

Value

an updated recipe

Examples

data(kennel_2020)

form <- as.formula("wl~.")

rec <- recipe(form, kennel_2020) |>
       step_fft_transfer_experimental(c(wl, baro, et), spans = 3) |>
       plate()
