geom_edge: Draw edges

In ggparty: 'ggplot' Visualizations for the 'partykit' Package

Description

Draws edges between children and parent nodes. Wrapper for ggplot2::geom_segment()

Usage

geom_edge(mapping = NULL, nudge_x = 0, nudge_y = 0, ids = NULL,
  show.legend = NA, ...)

Arguments

mapping	Mapping of x, y, xend and yend defaults to ids' and their parent's coordinates. Other mappings can be added here as aes().
nudge_x, nudge_y	Nudge labels.
ids	Choose which edges to draw by their children's ids.
show.legend	logical See layer().
...	Additional arguments for geom_segment().

Examples

library(ggparty)
data("WeatherPlay", package = "partykit")
sp_o <- partysplit(1L, index = 1:3)
sp_h <- partysplit(3L, breaks = 75)
sp_w <- partysplit(4L, index = 1:2)
pn <- partynode(1L, split = sp_o, kids = list(
  partynode(2L, split = sp_h, kids = list(
    partynode(3L, info = "yes"),
    partynode(4L, info = "no"))),
  partynode(5L, info = "yes"),
  partynode(6L, split = sp_w, kids = list(
    partynode(7L, info = "yes"),
    partynode(8L, info = "no")))))
py <- party(pn, WeatherPlay)

  geom_edge_label() +
  geom_node_label(aes(label = splitvar),
                  ids = "inner") +
