Calculate distance matrix — iDist • spStack

Computes the inter-site Euclidean distance matrix for one or two sets of points.

Usage

iDist(coords.1, coords.2, ...)

coords.1: an \(n\times p\) matrix with each row corresponding to a point in \(p\)-dimensional space.
coords.2: an \(m\times p\) matrix with each row corresponding to a point in \(p\) dimensional space. If this is missing then coords.1 is used.
...: currently no additional arguments.

The \(n\times n\) or \(n\times m\) inter-site Euclidean distance matrix.

n <- 10
p1 <- cbind(runif(n),runif(n))
m <- 5
p2 <- cbind(runif(m),runif(m))
D <- iDist(p1, p2)
