g <- group_by(iris, Species)

# ---- tango()
g %>%
  tango(rumba(Sepal.Length, mean = mean, median = median))

# select the first column, control the result names
# with the glue() model
g %>%
  tango(rumba(1, mean = mean, median = median, .name = "{var}_{fun}"))

g %>%
  tango(Sepal.Width = zumba(Sepal.Width, mean = mean, median = median))

# ---- jive()
g %>%
  jive(
    rumba(Sepal.Width, five = fivenum, quantile = quantile)
