data(canada)
canada <- canada[canada$h1=="Canada",]
canada$codes <- canada$h3
v1 <- vt_input_from_df(canada, hierachyVar0 = "h1", hierachyVar1 = "h2",
  hierachyVar2 = "h3", colorVar = "color",weightVar = "weight",
  labelVar = "codes")
 colnames(canada) <- c("hier1","hier2","hier3","col","w","cod")
v2 <- vt_input_from_df(canada, hierachyVar0 = "hier1", hierachyVar1 = "hier2",
