CHILD-class: Class '"CHILD"'

In coffeemuggler/RCHILD: Functions for flexible use of the landscape evolution model CHILD

Description

A CHILD object comprises all data sets from a model run output. CHILD saves a series of ASCII-files in a common directory. A CHILD object can be created from a model run output file collection with the function read.CHILD.

Usage

CHILD(...)

Arguments

...

Objects from the Class

Objects can be created by calls of the form CHILD(...).
