geom_sankey_bump

Description

Creates a sankey bump plot which visualize flows between nodes. Each observation needs to have a 'x' aesthetic as well as a 'next_x' column which declares where that observation should flow. Also, each observation should have a 'node' and a 'next_node' aesthetic which provide information about which group in the y-direction.

Usage

geom_sankey_bump(
  mapping = NULL,
  data = NULL,
  position = "identity",
  na.rm = FALSE,
  show.legend = NA,
  smooth = 8,
  type = "sankey",
  inherit.aes = TRUE,
  ...
)

Arguments

mapping	Provide you own mapping. Both x and y need to be numeric.
data	Provide you own data.
position	Change position.
na.rm	Remove missing values.
show.legend	Show legend in plot.
smooth	How much smooth should the curve have? More means steeper curve.
type	Either 'sankey' or 'alluvial'.
inherit.aes	Should the geom inherit aesthetics.
...	Other arguments to be passed to the geom.

Details

Other important arguments are; 'space' which provides the space between nodes in the y-direction; 'shift' which shifts nodes in the y-direction.

Value
