plot
method for party
objects with
extended facilities for plugging in panel functions.## S3 method for class 'party':
plot(x, main = NULL,
terminal_panel = node_terminal, tp_args = list(),
inner_panel = node_inner, ip_args = list(),
edge_panel = edge_simple, ep_args = list(),
drop_terminal = FALSE, tnex = 1,
newpage = TRUE, pop = TRUE, gp = gpar(), ...)
## S3 method for class 'constparty':
plot(x, main = NULL,
terminal_panel = NULL, tp_args = list(),
inner_panel = node_inner, ip_args = list(),
edge_panel = edge_simple, ep_args = list(),
type = c("extended", "simple"), drop_terminal = NULL,
tnex = NULL, newpage = TRUE, pop = TRUE, gp = gpar(),
...)
## S3 method for class 'simpleparty':
plot(x, digits = getOption("digits") - 4, tp_args = NULL, ...)
party
or constparty
.extended
tries to visualize the distribution of the
response variable in each terminal node whereas simple
only gives some summary ifunction(node)
plotting the terminal nodes.
Alternatively, a panel generating function of class
"grapcon_generator"
that is called withterminal_panel
if this
is a "grapcon_generator"
object.function(node)
plotting the inner nodes.
Alternatively, a panel generating function of class
"grapcon_generator"
that is called with arinner_panel
if this
is a "grapcon_generator"
object.function(split, ordered = FALSE, left = TRUE)
plotting the edges.
Alternatively, a panel generating function of class
"grapcon_gen
edge_panel
if this
is a "grapcon_generator"
object.grid.newpage()
should be called.plot
method for party
objects provides an
extensible framework for the visualization of binary regression trees. The
user is allowed to specify panel functions for plotting terminal and inner
nodes as well as the corresponding edges. Panel functions for plotting
inner nodes, edges and terminal nodes are available for the most important
cases and can serve as the basis for user-supplied extensions, see
node_inner
. More details on the ideas and concepts of panel-generating functions and
"grapcon_generator"
objects in general can be found in Meyer, Zeileis
and Hornik (2005).
