Return Contents of Selected Nodes of a Tree Object

DESCRIPTION:

Generates a list of all the information contained in the frame component of the tree object for that node.

USAGE:

browser.tree(tree, nodes, digits=.Options$digits - 3) 

REQUIRED ARGUMENTS:

tree
fitted model object of class tree. This is assumed to be the result of some function that produces an object with the same named components as that returned by the tree() function.

OPTIONAL ARGUMENTS:

nodes
an integer vector containing indices (node numbers) of all nodes for which contents are desired. If missing, nodes are chosen interactively by the user.
digits
number of significant digits to include in numerical labels.

VALUE:

A named (by node) list, each element of which shows all the information contained in the frame component of the tree object for that node. If the nodes argument is supplied, a data frame is returned consisting of those rows of frame corresponding to the specified nodes.

GRAPHICAL INTERACTION:

A dendrogram of tree is expected to be visible on the graphics device, and a graphics input device (eg a mouse) is required. Clicking (the selection button) on a node selects that node. This process may be repeated any number of times. Clicking the exit button will stop the selection process. See help(.Device) for specific details on graphic input.
