Description

Add Spike Histograms and Extended Box Plots to ggplot

Usage

addggLayers(
  g,
  data,
  type = c("ebp", "spike"),
  ylim = layer_scales(g)$y$get_limits(),
  by = "variable",
  value = "value",
  frac = 0.065,
  mult = 1,
  facet = NULL,
  pos = c("bottom", "top"),
  showN = TRUE
)

Arguments

g	a ggplot object
data	data frame/table containing raw data
type	specifies either extended box plot or spike histogram. Both are horizontal so are showing the distribution of the x-axis variable.
ylim	y-axis limits to use for scaling the height of the added plots, if you don't want to use the limits that ggplot has stored
by	the name of a variable in data used to stratify raw data
value	name of x-variable
frac	fraction of y-axis range to devote to vertical aspect of the added plot
mult	fudge factor for scaling y aspect
facet	optional faceting variable
pos	position for added plot
showN	sete to FALSE to not show sample sizes

Details

For an example see this. Note that it was not possible to just create the layers needed to be added, as creating these particular layers in isolation resulted in a ggplot error.

Value

the original ggplot object with more layers added
