r - r用ggridge绘制错误不同的行数

Question

使用 ggridges 时，我收到一个错误，说参数暗示不同的行数：2、1536

知道发生了什么吗？

Picking joint bandwidth of 0.181
Don't know how to automatically pick scale for object of type quosure/formula. Defaulting to continuous.
Error in data.frame(..., check.names = FALSE) : 
  arguments imply differing number of rows: 2, 1536

library(ggplot2)
library(ggridges)

ggplot(iris, aes(x = Sepal.Length, y = Species)) + geom_density_ridges()



 packageVersion("ggplot2")
[1] ‘2.2.1’
> packageVersion("ggridges")
