Elements in a set not present in the other set. Equivalent to
setdiff().
Usage
subtract(object, set_in, not_in, ...)
# S4 method for 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
Name of the new set. By default it adds a "C".
- keep
Logical value to keep all the other sets.
- keep_relations
A logical value if you wan to keep old relations.
- keep_elements
A logical value if you wan to keep old elements.
- keep_sets
A logical value if you wan to keep old sets.
Methods (by class)
subtract( object = TidySet, set_in = characterORfactor, not_in = characterORfactor ): Elements present in sets but not in other sets
