Returns a full NxN matrix of Euclidean distances among the rows of X.
No block-based exclusion is performed.
Usage
# S3 method for class 'euclidean'
pairwise_dist(obj, X)
Arguments
- obj
A distance function object of class c("euclidean", "distfun").
- X
A numeric matrix (rows = observations, columns = variables).
Value
An N x N numeric matrix of pairwise Euclidean distances.
Details
This function simply calls dist(X) internally and converts it to a matrix via as.matrix().
Examples
X <- matrix(rnorm(100), 10, 10)
dist_obj <- eucdist()
dist_matrix <- pairwise_dist(dist_obj, X)
