perpendicularDistanceIZ-methods: Methods for "'perpendicularDistanceIZ'" Object Construction...

Description Methods


This is the one method for generic function perpendicularDistanceIZ in Package ‘sampSurf’ that allows for creation of objects of class "perpendicularDistanceIZ."


signature(downLog = "downLog", pds = "perpendicularDistance")


                        description = 'inclusion zone for down log perpendicular distance sampling',
                        spID = paste('pds',.StemEnv$randomID(),sep=':'),
                        spUnits = CRS(projargs=as.character(NA)),
                        pdsType = .StemEnv$pdsTypes,
                        ... )
  • downLog: An object of class "downLog" for which the inclusion zone is to be determined.

  • pds: An object of class "perpendicularDistance" that supplies the information on the perpendicular distance method for constructing the inclusion zone.

  • 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.

  • pdsType: A character string that specifies the type of perpendicular distance sampling used with regard to the selection (i.e., probability proportional to...) of the log. It can be one of "volume", "surfaceArea" or "coverageArea". (See also .StemEnv$pdsTypes for legal types.)

  • dots: Arguments to be passed on.
