zoneModifnonIso: zoneModifnonIso

In geozoning: Zoning Methods for Spatial Data

Description

zoneModifnonIso

Usage

zoneModifnonIso(K, qProb, map, zoneClose, iC, simplitol = 0.001, disp = 0)

Arguments

K	zoning object (such as returned by calNei function)
qProb	probability vector used to generate quantile values
map	object returned by function genMap
zoneClose	indices of close zones
iC	current zone index
simplitol	tolerance for spatial polygons geometry simplification
disp	0: no info, 1: detailed info

Details

modify non isolated zone (depends on distIsoZ parameter) so that it is joined to the closest neighbour zone with the same label.

Value

a zoning object

Examples

data(mapTest)
qProb=c(0.2,0.5)
ZK = initialZoning(qProb, mapTest)
K=ZK$resZ
Z=K$zonePolygone
plotZ(Z)
resP=detZoneClose(6,Z,K$zoneNModif) # zone 6 is close to zone 5 and zone 7
zoneClose = resP$zoneClose
kmi = zoneModifnonIso(K,qProb,mapTest,zoneClose,6,disp=1)
plotZ(kmi$zonePolygone) # zones 6 and 7 are joined into new zone 6
# now it is the turn of zone 5
Z=kmi$zonePolygone
resP=detZoneClose(5,Z,kmi$zoneNModif) # zone 5 is close to zone 7 and zone 6
kmi2 = zoneModifnonIso(kmi,qProb,mapTest,resP$zoneClose,5,disp=1)
plotZ(kmi2$zonePolygone) # zones 5 and 6 are joined into new zone 5
