Misclassifications by a Classification Tree

Report the number of mis-classifications made by a classification tree, either overall or at each node.

misclass.tree(tree, detail = FALSE)

`tree`	Object of class `"tree"`, representing a classification tree.
`detail`	If false, report overall number of mis-classifications. If true, report the number at each node.

The quantities returned are weighted by the observational weights if these are supplied in the construction of tree.

Either the overall number of misclassifications or the number for each node.
