boxplot不会用ggvis显示

Question

我正在尝试使用ggvis创建一个盒子图，即使只是一个简单的例子，我似乎无法查看一个

library(dplyr)
library(ggplot2)
library(shiny) #I think this is required? not sure
data.frame(theVar = c(1,5:10,15)) %>% ggvis(x = ~theVar) #makes a histogram

data.frame(theVar = c(1,5:10,15)) %>% ggvis(x = ~theVar) %>% layer_boxplots()

Error: Can't find prop y.update

强制y变量：

data.frame(theVar = c(1,5:10,15)) %>% ggvis(x = ~theVar,y=~theVar) %>% layer_boxplots()

似乎把它变成了间隔？不知道它在做什么，但它不是一个箱形图，箱形图也不需要X和Y ......

Answer 1

如果您有一个变量，则必须将变量用于y，并为x指定一个虚拟变量：

library(ggvis)
data.frame(theVar = c(1,5:10,15)) %>% ggvis(y = ~theVar, x = ~ 1) %>% layer_boxplots()
