step_fft_coherence — step_fft_coherence • hydrorecipes

estimates the coherence between terms.

Usage

step_fft_coherence(.rec, terms, 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.
role: character - the name of the role
...: additional arguments

Value

an updated recipe

Examples


data(kennel_2020)

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

formula <- as.formula(wl~baro + et)
frec = recipe(formula = formula, data = kennel_2020) |>
  step_fft_pgram(c(wl, baro, et), spans = 7) |>
