如何在 rbokeh 中创建嵌套/分组类别的箱线图？

Question

I need to create a nested category box-plot where the x-axis is a combination of 2 factor(category) groups. In ly_boxplot() , the x argument can either be a numeric vector or a factor . Is there a way that it will accept a combined factor, say, of 2 or more factors?

The picture below is taken from this link .

How can I create such a plot using rbokeh library in R?

Answer 1

Use the interaction function.

library(rbokeh)
figure(ylab = "Length (mm?)", xlab="Dose (mg/day) : Supplement") %>%
  ly_boxplot(len, interaction(dose,supp), data = ToothGrowth)
