Creating a two-level Treemap in Highcharter R with data_to_hierarchical
问题
我正在尝试使用highcharter包中的data_to_hierarchical()函数在R中创建一个两级Treemap。它需要有两个级别 - 最顶层是Level1变量，然后可以点击查看第二个Level2变量：
如何使它成为两级的？我已经进行了很多搜索，但关于在R中制作高级图表Treemap的信息相互冲突且存在已弃用的函数，我无法找到答案。
可重现的代码：
library(tidyverse)library(highcharter)set.seed(110)ex <- data.frame(Level1 = rep(paste0("Country", seq(1:5)), each = 5),Level2 = rep(paste0("Sector", seq(1:5)), 5),Percentage = runif(25, 0, 1))ex %>%data_to_hierarchical(c(Level1, Level2), Percentage) %>%hchart(type = "treemap")

I'm attempting to create a two-level Treemap in R using data_to_hierarchical() from the highcharter package. It needs to have two levels - the topmost being the Level1 variable, which can then be clicked to view the second Level2 variable:
How can I make it two-level? I've done a lot of googling, but there's a lot of conflicting information and depreciated functions regarding making highcharts treemaps in R, and I haven't been able to find an answer.
Reproducible code:
library(tidyverse)library(highcharter)set.seed(110)ex <- data.frame(Level1 = rep(paste0("Country", seq(1:5)), each = 5),Level2 = rep(paste0("Sector", seq(1:5)), 5),Percentage = runif(25, 0, 1))ex %>%data_to_hierarchical(c(Level1, Level2), Percentage) %>%hchart(type = "treemap")

我通过向我的 hchart() 函数添加allowTraversingTree、levelIsConstant 和 levels 参数来解决了这个问题：
library(tidyverse)library(highcharter)set.seed(110)ex <- data.frame(Level1 = rep(paste0("Country", seq(1:5)), each = 5),Level2 = rep(paste0("Sector", seq(1:5)), 5),Percentage = runif(25, 0, 1))ex %>%data_to_hierarchical(c(Level1, Level2), Percentage) %>%hchart(type = "treemap",allowTraversingTree = T,levelIsConstant = F,levels = list(list(level = 1, dataLabels = list(enabled = TRUE,format = "{point.name}<br>{point.value}%"), borderColor = "black", borderWidth = 2),list(level = 2, dataLabels = list(enabled = FALSE))))

I solved this by adding the allowTraversingTree, levelIsConstant, and levels arguments to my hchart() function:
library(tidyverse)library(highcharter)set.seed(110)ex <- data.frame(Level1 = rep(paste0("Country", seq(1:5)), each = 5),Level2 = rep(paste0("Sector", seq(1:5)), 5),Percentage = runif(25, 0, 1))ex %>%data_to_hierarchical(c(Level1, Level2), Percentage) %>%hchart(type = "treemap",allowTraversingTree = T,levelIsConstant = F,levels = list(list(level = 1, dataLabels = list(enabled = TRUE,format = "{point.name}<br>{point.value}%"), borderColor = "black", borderWidth = 2),list(level = 2, dataLabels = list(enabled = FALSE))))
