Plot method for randomForest objects
Plot the error rates or MSE of a randomForest object
## S3 method for class 'randomForest' plot(x, type="l", main=deparse(substitute(x)), ...)
x |
an object of class |
type |
type of plot. |
main |
main title of the plot. |
... |
other graphical parameters. |
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.
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.
