The 'Sortchildren' method

Implemented under Windows only

Argument: See text
Result: None

Valid for: Tree

The Sortchildren method causes the children of a particular node to be sorted.

The argument is a two-element nested vector, or a character vector or integer scalar. The first element identifies the node, and can be a node ID or the character vector 'root'. The second element is optional. If supplied, it should be 'recurse' to indicate that the operation should be applied recursively to the children of the node.
