Visualization of Energy Trees

Description

Returns the plot of an object of class "etree".

Usage

## S3 method for class 'etree'
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(),
  ...
)

Arguments

`x`	An object of class `"etree"`, i.e., a fitted Energy Tree.
`main`	Optional title for the plot.
`terminal_panel`	Optional panel function of the form `function(node)` plotting the terminal nodes. Alternatively, a panel generating function of class `"grapcon_generator"` that is called with arguments `x` and `tp_args` to set up a panel function. By default, an appropriate panel function is chosen depending on the scale of the dependent variable.
`tp_args`	List of arguments passed to `terminal_panel` if this is a `"grapcon_generator"` object.
`inner_panel`	Optional panel function of the form `function(node)` plotting the inner nodes. Alternatively, a panel generating function of class `"grapcon_generator"` that is called with arguments `x` and `ip_args` to set up a panel function.
`ip_args`	List of arguments passed to `inner_panel` if this is a `"grapcon_generator"` object.
`edge_panel`	Optional panel function of the form `function(split, ordered = FALSE, left = TRUE)` plotting the edges. Alternatively, a panel generating function of class `"grapcon_generator"` that is called with arguments `x` and `ep_args` to set up a panel function.
`ep_args`	List of arguments passed to `edge_panel` if this is a `"grapcon_generator"` object.
`type`	Character specifying the complexity of the plot: `extended` tries to visualize the distribution of the response variable in each terminal node whereas `simple` only gives some summary information.
`drop_terminal`	Logical indicating whether all terminal nodes should be plotted at the bottom.
`tnex`	Numeric value giving the terminal node extension in relation to the inner nodes.
`newpage`	Logical indicating whether `grid.newpage()` should be called.
`pop`	Logical indicating whether the viewport tree should be popped before return.
`gp`	Graphical parameters.
`...`	Additional arguments.

Details

The plot() method for "etree" objects allows for the visualization of fitted Energy Trees, as returned by etree() or as contained in the ensemble element of a fitted Random Energy Forest.
