meanvar.rpart(tree, xlab="ave(y)", ylab="ave(deviance)", ...)
tree
|
fitted model object of class rpart . This is asumed to be the result
of some function that produces an object with the same named
components as that returned by the rpart function.
|
xlab
| x-axis label for the plot. |
ylab
| y-axis label for the plot. |
...
| additional graphical parameters may be supplied as arguments to this function. |
x
|
fitted value at terminal nodes (yval ).
|
y
| deviance of node divided by number of observations at node. |
label
|
node number.
