saveZK: saveZK function called by correctionTree

In hazaeljones/geozoning: Zoning Methods for Spatial Data

Description

saveZK function called by correctionTree

Usage

saveZK(map, K1, Z2, qProb, listOfZ, indCur, crit, cost, costL, nz, mdist,
  pErr = 0.9, optiCrit = 2, simplitol = 0.001)

Arguments

map	object returned by function genMap
K1	previous zoning
Z2	current zoning geometry (list of SpatialPolygons)
qProb	probability vector used to generate quantile values
listOfZ	list of zoning objects
indCur	index of new list element
crit	list of criteria
cost	list of costs
costL	list of per label costs
nz	list of number of zones
mdist	list of distance matrices
pErr	equality tolerance for distance calculations
optiCrit	criterion choice
simplitol	tolerance for spatial polygons geometry simplification

Details

Given a map object, a list of zonings, a current and a previous zoning, adds the current zoning to the list of zonings if it has at least 2 zones,after recalculating zone neighborhood and transferring zone labels.

Value

a list with components

listOfZ

updated list of zoning objects, first element corresponds to initial zoning, each other element is a list with each (last if ALL=FALSE) level zoning objects

mdist

list of initial distance matrix and all (last if ALL=FALSE) level distance matrices

crit

list of initial criterion and all (last if ALL=FALSE) level criteria

cost

list of initial cost and all (last if ALL=FALSE) level costs

costL

list of initial cost per label and all (last if ALL=FALSE) level costs per label

nz

list of initial number of zones and all (last if ALL=FALSE) level number of zones

Examples

data(mapTest)
# run zoning with 2 quantiles corresponding to probability values 0.4 and 0.7
criti=correctionTree(c(0.4,0.7),mapTest,LASTPASS=FALSE,SAVE=TRUE)
K1=criti$zk[[1]][[1]]#initial zoning
Z1=K1$zonePolygone
printZsurf(Z1) # 8 zones with 2 small zones (7 and 8)
Z2 = geozoning:::remove1FromZ(Z1,7,K1$zoneN)
printZsurf(Z2) #7 zones
indCur=2
newRes=geozoning:::saveZK(mapTest,K1,Z2,c(0.4,0.7),criti$zk,indCur,
        criti$criterion,criti$cost,criti$costL,criti$nz,criti$mdist)
newZ=newRes$listOfZ[[2]][[1]]$zonePolygone
printZsurf(newZ) #6 zones
