(This article was first published on Data visualization (in R), and kindly contributed to R-bloggers)
I published a short function to draw trophic networks with several levels, with links going from level n+1 to level n only. It will only be of interest for people working in ecology (but if you see another possible use, please let me know).
It is available here – with examples.
If I continue to publish at this rhythm, expect a brand new post around november!
