locUloc {geoCount} | R Documentation |
This function calculates the distance matrix between observed and predicting locations.
locUloc(loc, locp)
loc |
a matrix of n \times 2 which indicates the x-y coordinates of the observed locations; if a vector is used, it will be converted to matrix automatically |
locp |
a matrix of m \times 2 which indicates the x-y coordinates of the predicting locations; if a vector is used, it will be converted to matrix automatically |
This function calls the underlying C++ program to do the computation.
A m \times n matrix with the element e_{ij} indicating the distance between the ith predicting location and the jth observed locations.
