How to implement Knn-algorithm without using k-nn function in r

Question

Is there a website to which I can refer? Actually, I'm a newbie when it comes to R programming. I'm not sure how to do it without the k-nn function. I just use the knn function to find example code.

Answer 1

I created an example that demonstrates the algorithm's operation and how to use it in R. The data for my example is provided here.

students known data.frame(Major = c(rep("Arts",4", "Applied Science", 3), rep("Education",3), rep("Science",6));
The cost of tuition is equal to c(2000,2200,2100,1900,2800,3000,2900, 2500,2700,2600,3100,3200,3150,3000,3175,3300),
Age = c(20,18,22,21,24,23,21,19,19,21,20,18,17,21,24,23), GPA = c(3.55,3.40,3.30,3.50,2.90,3.05,2.50, 3.80,3.45,3.35,3.00,3.50,4.00,3.40,3.30),
