Description
This function prints an arbor object.

of class arbor.
Usage
print.arbor(x, minlength = 0, spaces = 2, cp,
digits = getOption("digits") - 3, ...)
Arguments
| x |
fitted model object of class arbor. This is assumed to be the result
of some function that produces an object with the same named
components as that returned by the arbor function.
|
| minlength |
the minimum length for abbreviation of character or factor variables.
See labels.arbor
