genData: generate data

In geozoning: Zoning Methods for Spatial Data

Description

generate data

Usage

genData(DataObj = NULL, seed = 0, nPoints = 450, typeMod = "Exp",
  Vpsill = 5, Vrange = 0.2, Vmean = 8, Vnugget = 0, Vanis = 1,
  boundary = list(x = c(0, 0, 1, 1, 0), y = c(0, 1, 1, 0, 0)),
  manualBoundary = FALSE)

Arguments

DataObj	=NULL: simulated data with given seed or a data frame with real data
seed	numeric value used to generate simulated data
nPoints	number of generated raw data points
typeMod	type of variogram model (see vgm) "Gau", "Sph", "Exp"
Vpsill	partial sill in variogram
Vrange	variogram range
Vmean	average data value
Vnugget	nugget in variogram
Vanis	anisotropy in variogram
boundary	list, contains x and y boundaries
manualBoundary	logical, if TRUE a manual boundary is drawn.

Details

description, a paragraph

Value

a list

tabData

data frame of generated or real data with x,y,z values. x is standardized between 0 and 1, y is standardized with the same ratio used for x

boundary

standardized boundary

VGMmodel

VGM variogram model

modelGen

RM transformed variogram model

ratio

ratio used to normalize x data

Examples

# simulate data with Gaussian model
resGene=genData(NULL,10,450,"Gau",5,0.2,8,0,list(x=c(0,0,1,1,0),y=c(0,1,1,0,0)),FALSE)
plot(resGene$tabData)
