Plot a tree object on the current graphical device
## S3 method for class 'tree':
plot(x, y = NULL, type = c("proportional", "uniform"), ...)
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. |
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.
