horizontalPointISIZ-methods: Methods for "'horizontalPointISIZ'" object construction in...

In sampSurf: Sampling Surface Simulation for Areal Sampling Methods

Description

The one constructor method that is available for creating valid objects of class "horizontalPointISIZ" is documented below. Please especially see the note on extra arguments that can be passed below.

Methods

signature(standingTree = "standingTree", angleGauge = "angleGauge")

usage...

horizontalPointISIZ(standingTree,
                    angleGauge,
                    antithetic = FALSE,
                    description = 'Inclusion zone for horizontal point importance sampling method',
                    spID = paste('hps.is',.StemEnv$randomID(),sep=':'),
                    spUnits = CRS(projargs=as.character(NA)),
                    ...)

• standingTree: An object of class "standingTree" for which the inclusion zone is to be determined.

• angleGauge: An object of class "angleGauge".

• antithetic: TRUE: use antithetic importance sampling; FALSE: just normal importance sampling.

• description: A character vector description of the object.

• spID: A unique identifier that will be used in displaying the spatial polygon for the inclusion zone component of the object.

• spUnits: A valid CRS object specifying the Coordinate Reference System. This defaults to NA, which means you want to use your own user-defined system, say for a sample plot located in the field.

• ...: Arguments to be passed on, especially those that can be used in the call to the importanceSampling constructor (and associated proxy function) for control of subsampling within the inclusion zone. This will take place when the grid cell estimates are established via IS within the corresponding izGrid method.
