geom_edge_label: Draw edge labels

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

Draw edge labels

Description

Label edges with corresponding split breaks

Usage

geom_edge_label(
  mapping = NULL,
  nudge_x = 0,
  nudge_y = 0,
  ids = NULL,
  shift = 0.5,
  label.size = 0,
  splitlevels = seq_len(100),
  max_length = NULL,
  parse_all = FALSE,
  parse = TRUE,
  ...
)

Arguments

mapping	Mapping of label label defaults to breaks_label. Other mappings can be added here as aes().
nudge_x, nudge_y	Nudge label.
ids	Choose which splitbreaks to label by their children's ids.
shift	Value in (0,1). Moves label along corresponding edge.
label.size	See ggplot2::geom_label().
splitlevels	Which levels of split to plot. This may be useful in the presence of many factor levels for one split break.
max_length	If provided breaks_label levels will be truncated to the specified length.
parse_all	Defaults to FALSE, in which case everything but the inequality signs of breaks_label are deparsed. If TRUE complete breaks_label are parsed.
parse	Needs to be true in order to parse inequality signs of breaks_label.
...	Additional arguments for ggplot2::geom_label().

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)
