plot.tree(x, type="", ...)
tree.
This is assumed to be the result of some function that produces
an object with the same named
components as that returned by the
tree function.
"u",
uniform spacing of nodes is used; default is nonuniform spacing
based on change of deviance of parent and children nodes.
x are
returned invisibly as a list
with components
x
and
y.
x
is produced on the current graphics device.
This function is a method for the generic function for class tree. It can be invoked by calling for an object x of the appropriate class, or directly by calling regardless of the class of the object.
zauto <- tree(Mileage ~ Weight + Disp., car.test.frame) plot(zauto) # plot on current graphics device text(zauto) # put some labels on the plot identify(zauto) # find out what car is where by clicking on plot
