"pointRelascope": Point Relascope SamplingA subclass of "'>ArealSampling" that can be used to
create objects that encapsulate all the parameters necessary for point
relascope sampling of down woody debris.
Objects can be created by calls of the form new("pointRelascope",
...), and while this is reasonable with this class because there are
no graphical slots, it is still not recommended. The preferred method
for creating new objects is via the pointRelascope constructor.
In addition to those slots in class "ArealSampling," the following are defined…
angleDegrees:Object of class "numeric": The
relascope angle in degrees such that \(0<\nu \le 90\) degrees.
angleRadians:Object of class "numeric": The
relascope angle in radians.
phi:Object of class "numeric": The area factor
multiplier, \(\phi\), for angle \(\nu\), as described in the
references below.
slFactor:Object of class "numeric": The
squared length factor, \(L\), defining the constant amount of
length-square per unit area (acre or hectare) as described in the
references below.
rwFactor:Object of class "numeric": The
reach:width ratio or factor that makes it simpler to keep track of
some of the more useful relascope angles, especially when
constructing a relascope.
