f_plot_alluvial: plot alluvial on tidy data

In erblast/oetteR: Collection of personal R functions

Description

plots a dataframe as an alluvial plot. All numerical variables are scaled, centered and YeoJohnson transformed before binning.

Usage

f_plot_alluvial(data, variables = names(data), col_id = NULL,
  max_variables = 20, bins = 5, bin_labels = c("LL", "ML", "M", "MH",
  "HH"), NA_label = "NA", order_levels = NULL,
  fill_by = "first_variable",
  col_vector_flow = f_plot_col_vector74(faint = F, greys = F),
  col_vector_value = RColorBrewer::brewer.pal(9, "Greys")[c(3, 6, 4, 7,
  5)])

Arguments

data	a dataframe
variables	vector denoting names and order of the plotted variables, Default: names(data)
col_id	character vector denoting id column
max_variables	maximum number of variables, Default: 20
bins	number of bins for numerical variables, Default: 5
bin_labels	labels for the bins from low to high, Default: c("LL", "ML", "M", "MH", "HH")
NA_label	character vector define label for missing data
order_levels	character vector denoting levels to be reorderer from low to high
fill_by	one_of(c('first_variable', 'last_variable', 'all_flows', 'values')), Default: 'first_variable'
col_vector_flow	HEX colors for flows, Default: f_plot_col_vector74(faint = F, greys = F)
col_vector_value	Hex colors for y levels/values, Default: RColorBrewer::brewer.pal(9, "Greys")[c(3, 6, 4, 7, 5)]
