Usage

step_multiply(
  .rec,
  terms,
  values = 1,
  role = "predictor",
  skip = FALSE,
  keep_original_cols = FALSE,
  ...
)

.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.
values: multiply column(s) by these values
role: character - the name of the role
skip: logical - should the step be skipped
keep_original_cols: logical - keep the original columns or replace them
...: additional arguments

an updated recipe

dat <- data.frame(x = rnorm(10), y = rnorm(10))

rec <- recipe(y~x, data = dat) |>
       step_multiply(x, value = 4)
