omnibusPDSIZ-class: Class "omnibusPDSIZ"

Description

This class holds the inclusion zone definition for the ‘omnibus perpendicular distance sampling’ method (Ducey et. al, 2008) for sampling down coarse woody debris.

Objects from the Class

Objects can be created by calls of the form new("omnibusPDSIZ", ...). However, this is not recommended because the objects are fairly complex. Instead, one can use the object constructor omnibusPDSIZ to create new objects.

Slots

This class is a direct descendent (subclass) of "perpendicularDistanceIZ" and adds no new slots to that definition. Please see the "'>perpendicularDistanceIZ" class definition for details.

Extends

Class "'>perpendicularDistanceIZ", directly. Class "'>pdsIZNull", directly. Class "'>downLogIZ", by class "perpendicularDistanceIZ", distance 2. Class "'>InclusionZone", by class "perpendicularDistanceIZ", distance 3.

Methods

izGrid

signature(izObject = "omnibusPDSIZ", tract = "Tract"): “InclusionZoneGrid” generic constructor
