Creates an alluvial 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_alluvial(
mapping = NULL,
data = NULL,
position = "identity",
na.rm = FALSE,
show.legend = NA,
space = 0,
width = 0.1,
smooth = 8,
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
- space
space between nodes in the y-direction
- width
width of nodes
- smooth
how much smooth should the curve have? More means steeper curve.
- inherit.aes
should the geom inherits aestethics
- ...
other arguments to be passed to the geo
