如何在R中的SankeyNetwork Flow中为链接着色

Question

我无法为链接添加颜色，尽管通过fl幸，我已经能够为节点着色。

my_color <- 'd3.scaleOrdinal()
   .domain(["2010", "2011", "2012", "2013", "2014"])
   .range(["blue", "pink", "green", "purple", "orange"])'

sankeyNetwork(Links = l3, Nodes = n3,
          Source = 'source',
          Target = 'target',
          Value = 'value',
          NodeID = 'name',
          units = 'ValueUSD',
          fontSize = 12,
          colourScale = my_color)

出现节点颜色，但不知道如何使链接着色。我希望链接的颜色基于年份，而不是基于国家/地区。

SankeyNetwork中来自NetworkD3软件包的选项受到限制。我建议调查“ plotly”包。在这里您可以找到一些示例：https://plot.ly/~alishobeiri/1591/plotly-sankey-diagrams/#/
