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.
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.
