fullChainSawIZ-methods: Methods for "'fullChainSawIZ'" object construction in Package...

In sampSurf: Sampling Surface Simulation for Areal Sampling Methods

Description

The one constructor method that is available for creating valid objects of class "fullChainSawIZ" is documented below. Note that because the inclusion zone for this method is exactly the same as that for the "sausageIZ" class (sausage sampling), the same arguments are used here as in that constructor.

Methods

signature(downLog = "downLog", plotRadius = "numeric")

usage...

fullChainSawIZ(downLog,
               plotRadius,
               nptsHalfCircle = 50,
               description = 'Inclusion zone for "fullChainSaw" sampling method',
               spID = paste('fcs', .StemEnv$randomID(), sep=':'),
               spUnits = CRS(projargs = as.character(NA)),
               ... )

• downLog: An object of class "downLog" which the inclusion zone is to be determined for under this method.

• plotRadius: The radius of the circular fixed-area plot in the correct units: feet for "English" and meters for "metric."

• nptsHalfCircle: The number of points to use in the half-circle at each end of the sausage-shaped inclusion zone for the polygon representation of the object.

• description: A character vector description of the object.

• spID: A unique identifier that will be used in displaying the spatial polygon 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.
