How to find common elements from multiple vectors?



🔎 How to Find Common Elements from Multiple Vectors 🔍
Have you ever found yourself needing to find the common elements from multiple vectors? 🤔 It may sound like a tricky task, but fear not! In this guide, I'll walk you through the process step by step, providing easy solutions and examples along the way. Let's dive in! 💪🏼
The Problem 🧩
So, the question at hand is: "How to find the common elements from multiple vectors?" 🤷♀️ It sounds like something you'd encounter while working with data or solving mathematical problems.
Let's take a look at the context of this question:
a <- c(1, 3, 5, 7, 9)
b <- c(3, 6, 8, 9, 10)
c <- c(2, 3, 4, 5, 7, 9)
The goal is to find the common elements from vectors a
, b
, and c
(in this case, 3 and 9).
The Solution 💡
To find the common elements from multiple vectors in R, we can use the intersect
function. This function takes in two or more vectors as arguments and returns a new vector containing the elements that are present in all of the input vectors. Pretty neat, huh? 😎
To solve our specific problem, we'll use the intersect
function like this:
common_elements <- intersect(a, b, c)
That's it! The common_elements
vector will now contain the common elements from vectors a
, b
, and c
. In this case, it will be c(3, 9)
.
Example Time 🌟
Let's see the solution in action with the vectors mentioned earlier. Here's the code:
a <- c(1, 3, 5, 7, 9)
b <- c(3, 6, 8, 9, 10)
c <- c(2, 3, 4, 5, 7, 9)
common_elements <- intersect(a, b, c)
print(common_elements)
Output:
[1] 3 9
As you can see, the print
statement gives us the desired result: 3
and 9
are the common elements among the vectors.
Your Turn! 🚀
Now it's your turn to give it a try! If you're dealing with multiple vectors and need to find the common elements, remember to use the intersect
function in R for a seamless solution.
