I want to draw a Sankey-diagramm in R, for which I would use the
It would be really nice to be able to
1. draw vertical lines (="edges") between nodes on the same x-axis
(T03-T04 in the example below) and
2. to invert the plot.
Now the "edge" between T03 and T04 is straight, but not vertical (1.).
I could invert the plot manually after drawing it, but there could
most likely be a more elegant solution (2.).
