calculate color for higher level rectangles from weighted average of lower level when type='value' about d3treer HOT 3 CLOSED

Try adding fun.aggregate:

tm <- treemap(mock, index = c("Country", "Industry"), vSize = "GDP", vColor = "Growth", 
              type = "value", palette = "Spectral", 
              fun.aggregate="weighted.mean")
d3tree2(tm, rootname = "World")

Thanks @ignacio82. @ellisp treemap was not originally designed for this since colors only appear at the lowest level. Fortunately @mtennekes quickly added in mtennekes/treemap#18. Would love feedback.

Perfect, exactly what I was looking for, thanks all.
