fullChainSawIZ-methods: Methods for “`fullChainSawIZ`” object construction in Package sampSurf

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.

Arguments

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.
