R: Plot method for randomForest objects

plot.randomForest {randomForest} | R Documentation

## Plot method for randomForest objects

### Description

Plot the error rates or MSE of a randomForest object

### Usage

    ## S3 method for class 'randomForest'
    plot(x, type="l", main=deparse(substitute(x)), ...)

### Arguments

`x` | an object of class `randomForest`.
`type` | type of plot.
`main` | main title of the plot.
`...` | other graphical parameters.

### Value

Invisibly, the error rates or MSE of the `randomForest` object. If the object has a non-null `test` component, then the returned object is a matrix where the first column is the out-of-bag estimate of error, and the second column is for the test set.

### Note

This function does not work for `randomForest` objects that have `type=unsupervised`.

If the `x` has a non-null `test` component, then the test set errors are also plotted.
