step_dummy_extract() creates a specification of a recipe step that will convert nominal data (e.g. character or factors) into one or more integer model terms for the extracted levels.

Usage

step_dummy_extract(
  recipe,
  ...,
  role = "predictor",
  trained = FALSE,
  sep = NULL,
  pattern = NULL,
  threshold = 0,
  other = "other",
  naming = dummy_extract_names,
  levels = NULL,
  keep_original_cols = FALSE,
  skip = FALSE,
  id = rand_id("dummy_extract")
)

Arguments

recipe

A recipe object. The step will be added to the sequence of operations for this recipe.

...

One or more selector functions to choose variables for this step. See selections() for more details.

role

Not used by this step since no new variables are created.

trained

A logical to indicate if the quantities for preprocessing have been estimated.

sep

Character vector containing a regular expression to use for splitting. strsplit() is used to perform the split. sep takes priority if pattern is also specified.

pattern

Character vector containing a regular expression used for extraction. gregexpr() and regmatches() are used to perform pattern extraction using perl = TRUE.

threshold

A numeric value between 0 and 1, or an integer greater or equal to one. If less than one, then factor levels with a rate of occurrence in the training set below threshold will be pooled to other. If greater or equal to one, then this value is treated as a frequency and factor levels that occur less than threshold times will be pooled to other.

other

A single character value for the "other" category.

naming

A function that defines the naming convention for new dummy columns. See Details below.

levels

A list that contains the information needed to create dummy variables for each variable contained in terms. This is NULL until the step is trained by prep().

keep_original_cols

A logical to keep the original variables in the output. Defaults to FALSE.

skip

A logical. Should the step be skipped when the recipe is baked by bake()? While all operations are baked when prep() is run, some operations may not be able to be conducted on new data (e.g. processing the outcome variable(s)). Care should be taken when using skip = TRUE as it may affect the computations for subsequent operations.

id

A character string that is unique to this step to identify it.

Value

An updated version of recipe with the new step added to the sequence of any existing operations.

Details

step_dummy_extract() will create a set of integer dummy variables from a character variable by extract individual strings by either splitting or extracting then counting those to create count variables.

Note that threshold works in a very specific way for this step. While it is possible for one label to be present multiple times in the same row, it will only be counted once when calculating the occurrences and frequencies.

This recipe step allows for flexible naming of the resulting variables. For an unordered factor named x, with levels "a" and "b", the default naming convention would be to create a new variable called x_b. The naming format can be changed using the naming argument; the function dummy_names() is the default.

Tidying

When you tidy() this step, a tibble with columns terms (the selectors or original variables selected) and columns (the list of corresponding columns) is returned. The columns is is ordered according the frequency in the training data set.

Case weights

This step performs an unsupervised operation that can utilize case weights. As a result, case weights are only used with frequency weights. For more information, see the documentation in case_weights and the examples on tidymodels.org.

  step_dummy_extract(artist, medium, sep = ", ") %>%
