This class holds the inclusion zone definition for the fixed-area circular plot method for sampling standing trees.
Objects can be created by calls of the form
...). However, this is not recommended
because the objects are fairly complex. Instead, one can use the object
circularPlotIZ to create new objects.
This class adds one slot to the "standingTreeIZ" class specification, please see the superclasses (see below) for more definitions.
Object of class
An object from the "
circularPlot". Please see the help for this
class for more information on the slots associated with circular
"InclusionZone", by class "standingTreeIZ", distance 2.
signature(x = "circularPlotIZ"): Return the area
of the circular plot inclusion zone.
signature(izObject = "circularPlotIZ", tract =
"Tract"): Create the raster grid object associated with the inclusion
signature(object = "circularPlotIZ"): Return
the object perimeter as a SpatialPolygons object.
signature(x = "circularPlotIZ", y = "missing"):
Plot the object.
signature(object = "circularPlotIZ"): Summary
report for the object.
