hybridDLPDSIZ-class: Class "hybridDLPDSIZ"

Description

This class holds the inclusion zone definition for the ‘hybrid distance limited perpendicular distance sampling’ method for sampling down coarse woody debris (Ducey et. al 2012). This class is fairly complicated because there are three possibilities for the components of the inclusion zone. It is best to read "The InclusionZone Class" vignette, along with the references for more information---the why's and wherefore's are not presented here, only the class documentation.

Objects from the Class

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

Slots

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

Extends

Class "'>distanceLimitedPDSIZ", directly. Class "'>perpendicularDistanceIZ", by class "distanceLimitedPDSIZ", distance 2. Class "'>downLogIZ", by class "distanceLimitedPDSIZ", distance 3. Class "'>pdsIZNull", by class "distanceLimitedPDSIZ", distance 3. Class "'>InclusionZone", by class "distanceLimitedPDSIZ", distance 4.

Methods

No methods defined with class "hybridDLPDSIZ" in the signature; instead see those defined for "'>distanceLimitedPDSIZ".
