Description

This documents the one method for generic function criticalHeightIZ in Package sampSurf that allows for creation of objects of class "'>criticalHeightIZ."

Arguments

Methods

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

usage… 

criticalHeightIZ(standingTree,
                 angleGauge,
                 referenceHeight = .StemEnv$referenceCHSIZ,
                 description = 'inclusion zone for critical height sampling method',
                 spID = paste('chs',.StemEnv$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".

  • referenceHeight: The height on the stem at which the inclusion zone is to be determined. Currently the choices are “butt” (default) or “dbh”. These are found in the argument assignment .StemEnv$referenceCHSIZ above.

  • 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.

  • dots: Arguments to be passed on.
