Usage

step_drop_columns(.rec, terms, role = "modify", ...)

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

rows <- 20
formula <- as.formula(y~x)

dat <- data.frame(x = rnorm(rows),
                  y = as.numeric(1:rows),
                  z = rnorm(rows))


frec = recipe(formula = formula, data = dat) |>
  step_drop_columns(x)
