Computes a full NxN matrix of correlation-based distances: 1 - cor(t(X), method=obj$method).
No block-based exclusion is performed here.
Usage
# S3 method for class 'cordist'
pairwise_dist(obj, X)
Arguments
- obj
A distance function object of class c("cordist", "distfun").
- X
A numeric matrix (rows = observations, columns = variables).
Value
An N x N numeric matrix of pairwise distances.
Details
This function calculates correlation distances among the rows of X.
If you have a block variable and wish to exclude same-block comparisons,
handle that after obtaining this full matrix (e.g., in second_order_similarity).
Examples
X <- matrix(rnorm(100), 10, 10)
dist_obj <- cordist(method="pearson")
dist_matrix <- pairwise_dist(dist_obj, X)
