In blasern/rdist: Calculate Pairwise Distances
is_metric R Documentation
Metric and triangle inequality
Description
Does the distance matric come from a metric
Usage
is_distance_matrix(mat, tolerance = .Machine$double.eps^0.5)
triangle_inequality(mat, tolerance = .Machine$double.eps^0.5)
Arguments
mat
The matrix to evaluate
tolerance
Differences smaller than tolerance are not reported.
Examples
data <- matrix(rnorm(20), ncol = 2)
dm <- pdist(data)
is_distance_matrix(dm)
triangle_inequality(dm)
dm[1, 2] <- 1.1 * dm[1, 2]
is_distance_matrix(dm)
