R: Plot a Tree Object

plot.tree {tree} | R Documentation

## Plot a Tree Object

### Description

Plot a tree object on the current graphical device

### Usage

    ## S3 method for class 'tree'
    plot(x, y = NULL, type = c("proportional", "uniform"), ...)

### Arguments

`x` | an object of class `"tree"`.
`y` | ignored. Used for positional matching of `type`.
`type` | character string. If this partially matches `"uniform"`, the branches are of uniform length. Otherwise they are proportional to the decrease in impurity.
`...` | graphical parameters.

### Value

An (invisible) list with components `x` and `y` giving the coordinates of the tree nodes.

As a side effect, the value of `type == "uniform"` is stored in the variable `.Tree.unif.?` in the global environment, where `?` is the device number.
