boxplot won't display with ggvis

问题

I'm trying to make a boxplot with ggvis and I can't seem to view one even with a simple example

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

forcing a y variable:

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

seems to turn it into intervals? not sure what its doing but it's not a boxplot, nor should a boxplot need an X and Y...

回答1:

If you have a single variable, you have to use your variable for y and specify a dummy for x:

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