What is the intersect() function in R?

Overview

The intersect() function in R determines the intersection of the subsets of a probability space. For example, intersect(A, B) returns the rows that are common to the subsets A and B.

Syntax

intersect(x, y, ...)
Syntax for the intersect() function in R

Parameter value

The intersect() function takes the following parameter values:

  • x , y: These are the data frame, or vector, objects that contain a sequence of elements. These are required values.
  • ...: This represents further arguments that are passed to or from other R methods. This is an optional value.

Return value

The intersect() function returns a vector, data frame, or a probability subset with the same data type as the input argument.

Code example

# Creating subsets 

set_A = c('the', 'foo', 'the', 'bar', 'and', 'the', 'baz')

set_B = c('The', 'Foo', 'the', 'Bar', 'and', 'the', 'Baz')



# Implementing the intersect() function 

intersect(set_A, set_B)

Code explanation

  • Lines 2–3: We create subsets set_A and set_B.
  • Line 6: We obtain the intersection of the subsets using the intersect() function.
