Subtract

Description

Elements in a set not present in the other set. Equivalent to setdiff().

Usage

subtract(object, set_in, not_in, ...)

## S4 method for signature 'TidySet,characterORfactor,characterORfactor'
subtract(
  object,
  set_in,
  not_in,
  name = NULL,
  keep = TRUE,
  keep_relations = keep,
  keep_elements = keep,
  keep_sets = keep
)

Arguments

object

A TidySet object.

set_in

Name of the sets where the elements should be present.

not_in

Name of the sets where the elements should not be present.

...

Placeholder for other arguments that could be passed to the method. Currently not used.

name
