geom_edge_label {ggparty}

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 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.
