how to formating data to produce sankey diagram using NetworkD3 library R : I have this [data][1], and I'm trying to produce a Sankey Diagram using the NetworkD3 package with this simple code:

    sankeyNetwork(Links = landuse$links, Nodes = landuse$nodes, Source = "source",
                  Target = "target", Value = "value", NodeID = "name",
                  units = "km²", fontSize = 12, nodeWidth = 30)

I received this message:

    Warning message:
    It looks like Source/Target is not zero-indexed. This is required in JavaScript and so your plot may not render.

But even if I zero-indexed the target/source nothing is redering in dev. I have the data in the same format like in this [example][2], so I would like to know the possible problem.
