.distance_meters_from_coords

Helper function gets the distance in meter between
pairs of coordinates. Note that <code>coords</code> must be a matrix
or frame, where the first col is longitude and the second
column is latitude

Provides utilities for manipulating time series of location-based counts of events to detect geo-spatial clusters. Significance of these clusters is determined using a set of models that classify based on a learned relationship between observed and the log(observed/expected) ratio of counts. The approach implemented here is similar to prospective space-time estimation of clusters using the scan statistic.
