How to Calculate Euclidean Distance in R

To calculate euclidean distance in R, you can declare function manually.

The following method shows how you can do it with syntax.

Method: Declare Function

euclidean <- function(x1, x2) {
  sqrt(sum((x1 - x2)^2))
}

The following example shows how to calculate euclidean distance in R.

Calculate Euclidean Distance

Let’s see how to calculate euclidean distance between two vector in R:

# Declare euclidean function
euclidean <- function(x1, x2) {
  sqrt(sum((x1 - x2)^2))
}

# Declare vector
a <-c(78,85,89,96,74,75)
b <-c(65,66,64,69,70,61)

# Calculate euclidean distance
d <- euclidean(a,b)

# Show euclidean distance
print(d)

Output:

[1] 45.78209

As the output shows euclidean distance between two vectors that we declare in above code.
