euclidean distances

Hi everyone, I have some exercises to do of multidimensional scaling and i'm trying to check if, given data of dissimilarities between European cities, they are euclidean distances and if they aren't, how to obtain euclidean distances from them. Any help is appreciated. Thanks!!!

Hi, see the sf package:

Compute geometric measurements — geos_measures • sf (

In the simplest case, for a pair of points

(points <- matrix(c(1, 2, 4, 6), nrow = 2, byrow = TRUE))
#>      [,1] [,2]
#> [1,]    1    2
#> [2,]    4    6
(euclidean_distance <- dist(points))
#>   1
#> 2 5
