How to find Intersection of Two Sets in R ?

Answer

In R, you can find the intersection of two sets using the intersect function.

✐ Examples

1 Find Intersection of Two Sets using intersect function

In this example,

We define two sets, set1 and set2, using R's set notation.
We use the intersect function to find the common elements between set1 and set2.
The result is stored in a new set named intersection.
We print the elements of intersection to display the intersection of the two sets.

R Program

set1 <- c(1, 2, 3, 4)
set2 <- c(3, 4, 5, 6)

intersection <- intersect(set1, set2)

print(paste('Intersection of set1 and set2:'))
print(intersection)

Output

[1] 3 4

2 Find Intersection of Two Sets using custom implementation

In this example,

We create two sets, set1 and set2, using R's set notation.
We define a custom function named find_intersection that takes two sets as input parameters.
Inside the find_intersection function, we use the %in% operator to find elements from set1 that are present in set2.
The filtered elements are returned as the intersection of the two sets.

R Program

set1 <- c(1, 2, 3, 4)
set2 <- c(3, 4, 5, 6)

find_intersection <- function(set1, set2) {
  return(set1[set1 %in% set2])
}

intersection <- find_intersection(set1, set2)

print(paste('Intersection of set1 and set2:'))
print(intersection)

Output

[1] 3 4
