[R] Confussion matrix in tree clasiffication

[David L Carlson]

Use predict.tree() with type="class" on the object returned by tree(). Then use that to construct a cross tabulation against the original data. If you provide a reproducible example with data, I could be more specific.

I want to create a confussion matrix after using the tree package to create
a clasiffication tree, but I´m not sure of how to create this matrix.

Thanks
Jesús
