How to get percentages on the y axes in an alluvial or sankey plot?

Question

I realized this graph using ggplot2 and I\'d like to change y axes to percentages, from 0% to 100% with breaks every 10. I know I can use:

+ scale_y         


        

Answer 1

I assume You will need to create a new column of the percentages, by taking the total number of rows, and then dividing each "value" in your column by the total to get what percentage it represents.
