db.prop.thresh {RGeoS}R Documentation

Generates the thresholds through Rule

Description

Generates the thresholds through the Rule

Usage

db.prop.thresh(db, dbprop=NA, rule = rule.input(), model = NA, props = NA, 
flag.stat = TRUE, radix = NA, modify.target = TRUE)

Arguments

db

The db-class where the thresholds will be stored

dbprop

The db-class where the proportion variables must be located in the non-stationary case

rule

The rule-class structure which defines the Lithotype rule

model

The model-class structure containing the Model information for the first underlying gaussian random function. This model must only be provided when the Lithotype Rule refers to a Standard Rule (for the calculation of the correlation coefficient between the two underlying gaussians, if any) or for the Shadow Rule. Otherwise this argument is not necessary.

props

Array giving the (constant) proportions of the different facies involved in the Lithotype rule

flag.stat

Should be set to TRUE in the stationary case where the proportions should be defined as input arguments. When set to FALSE, the output db-class structure must contain N proportion variables (where N is also the number of facies)

radix

Radix of the name given to the facies outcome stored in the output Db.

modify.target

When TRUE, the facies results are set as new target variables in the output Db.

Value

The data Db where the thresholds have been added. The number of thresholds is equal to the twice the number of facies multiplied by the number of gaussian random functions (from Rule).
