MeanVarWPts: MeanVarWPts

In geozoning: Zoning Methods for Spatial Data

Description

MeanVarWPts

Usage

MeanVarWPts(map, zone, w = NULL)

Arguments

map	object returned by function genMap
zone	SpatialPolygons defining a zone
w	weighting vector (default NULL)

Details

computes (weighted) mean and variance of zone data

Value

a list with components

mean

(weighted) mean of the within zone attribute value

var

(weighted) variance of the within zone attribute value

Examples

data(resZTest)
K=resZTest
Z=K$zonePolygone
data(mapTest)
MeanVarWPts(mapTest,Z[[1]])
# Weights are areas of the Voronoi polygons corresponding to data points
MeanVarWPts(mapTest,Z[[1]],mapTest$krigSurfVoronoi) #slightly different result
