Range frames and quartile frames

A range frame draws an axis line between the smallest and largest observed values. Tufte's quartile frame adds breaks at the quartiles, so the axis also shows the five-number summary.

Usage

geom_rangeframe(
  mapping = NULL,
  data = NULL,
  stat = "identity",
  position = "identity",
  ...,
  sides = "bl",
  na.rm = FALSE,
  show.legend = NA,
  inherit.aes = TRUE
)

geom_quartileframe(
  mapping = NULL,
  data = NULL,
  stat = "identity",
  position = "identity",
  ...,
  sides = "bl",
  gap = 0.01,
  na.rm = FALSE,
  show.legend = NA,
  inherit.aes = TRUE
)

Arguments

mapping, data, stat, position, na.rm, show.legend, inherit.aes, ...

Standard ggplot2 layer arguments. See layer().

sides

Which axes to draw, as a string containing any of "b" (bottom), "l" (left), "t" (top) and "r" (right). Defaults to "bl".

gap

For geom_quartileframe(), the width of the break at each quartile, in npc units of the panel. Defaults to 0.01.

Value

A ggplot2 layer.

Details

Use these with theme_tufte(), which has no axis lines by default. With another theme, turn off its panel border and axis lines if you want only the range frame.

See also

quartile_breaks(), which puts the axis labels in the same places the quartile frame breaks.
