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.septakes priority ifpatternis also specified.- pattern
Character vector containing a regular expression used for extraction.
gregexpr()andregmatches()are used to perform pattern extraction usingperl = 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
thresholdwill be pooled toother. If greater or equal to one, then this value is treated as a frequency and factor levels that occur less thanthresholdtimes will be pooled toother.- 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 isNULLuntil the step is trained byprep().- 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 whenprep()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 usingskip = TRUEas 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.
