Description Usage Arguments Format Examples

This function allows you to plot an alluvial/Sankey diagram

1	data(melt_df)

`df`	A dataframe containing each variable as a column; must be in molted form (see reshape package for details)
`x_axis`	the column in df containing the x axis information
`grouping`	the column in df containing the group identity information
`weights`	the column containing the y axis information
`plot_title`	str; title of your plot
`xlab`	str; x-axis label
`ylab`	str; y-axis label
`axis_breaks`	vector of how the x axis should be partitioned
`has_lines`	if TRUE, includes vertical line breaks separating along the axis_breaks
`line_breaks`	a vector that contains the x-values for where the lines should be manually placed. Only functional if has_lines = TRUE
`add_values`	if TRUE, includes values of the weights corresponding to the alluvium strata
