standingTree: Generate Objects of Class "'standingTree'"
In sampSurf: Sampling Surface Simulation for Areal Sampling Methods

Description Usage Arguments Details Value Author(s) References See Also Examples

This generic function has methods based on the signature formal argument object. It is used as a constructor function for objects that are of class "standingTree". There are two methods that should be used in preference to new to insure a valid object.

1	standingTree(object, ...)

`object`	This is the signature formal argument, see the methods for more details.
`...`	Formal arguments that are different for each method, see those for details.

standingTree is defined completely with respect to the signature of its methods standingTree-methods. Methods are available for data.frame, and missing signatures. Other methods can obviously be added for other signatures as necessary.

A valid object of class "standingTree."
