iDist: Euclidean distance matrix

In spBayes: Univariate and Multivariate Spatial-Temporal Modeling

Euclidean distance matrix

Description

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

Usage

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

Arguments

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.

Value

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