🔎 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.

Feel free to experiment with different vectors and see the magic happen. 😉 And don't forget to share your experience or any other cool tips you discover in the comments below. Let's learn together! 🌟
