loopQ3: loopQ3

In geozoning: Zoning Methods for Spatial Data

Description

loopQ3

Usage

loopQ3(map, disp = 1, step = 0.075, minSize = 0.012, minSizeNG = 0.001,
  QUIET = F)

Arguments

map	object returned by function genMa
disp	0: no info, 1: some info, 2: detailed info
step	loop increment
minSize	zone area threshold under which a zone is too small to be manageable
minSizeNG	zone area threshold under which a zone will be removed
QUIET	run in silence-no display

Details

exploratory loop on probability values associated to quantiles. Performs map zonings for each value of the 3 quantile loop (yielding a 4-label zoning). see also loopQ1, loopQ2, loopQ4, loopQ5 for loops with a different number of labels

Value

a matrix with 8 columns and as many rows as loop elements. Columns contain the following values calculated for each quantile vector: criterion, cost, cost per label, number of zones, quantile associated probability values and number of non degenerated quantiles.

Examples

# not run, take a while - >5s CPU
seed=10
map=genMap(DataObj=NULL,seed=seed,disp=FALSE,krig=1)
loopQ3(map,step=0.1,disp=0,QUIET=TRUE)
