plot_meta_sankey: Plot metadata factors as a sankey diagram.

In elsayed-lab/hpgltools: A pile of (hopefully) useful R functions

Plot metadata factors as a sankey diagram.

Description

This provides two implementations of a sankey plot, one interactive and one using ggplot2.

Usage

plot_meta_sankey(
  design,
  factors = c("condition", "batch"),
  fill = "node",
  font_size = 18,
  node_width = 30,
  color_choices = NULL,
  drill_down = TRUE
)

Arguments

design	Metadata from which to extract the categories/numbers.
factors	Factors/columns in the metadata to count and plot.
fill	Use either the current or next node for coloring the transitions.
font_size	Chosen font size, perhaps no longer needed?
node_width	Make nodes more or less rectangular with this.
color_choices	Either a named vector of states and colors, or NULL (in which case it will use viridis.)
drill_down	When true, this will end in the product of the factor levels number of final states. (e.g. if there are 2 sexes, 3 visits, and 4 genotypes, there will be 2, 6, 24 states going from right to left). If FALSE, there will be 2,3,4 states going from right to left.

Value

List containing a couple of plots, one interactive, one gg.
