在'geom_bar（）中找不到对象`

我想将

prop

映射到条形图上的y轴，但我一直得到“未找到对象”错误。如何修复代码？谢谢大家!

dput(starwars_age)
structure(list(`Age Response` = c("> 60", "18-29", "30-44", "45-60"
), n = c(193L, 180L, 207L, 240L), prop = c(0.206196581196581, 
0.192307692307692, 0.221153846153846, 0.256410256410256)), row.names = c(NA, 
-4L), class = c("tbl_df", "tbl", "data.frame"))

starwars_age %>%
  mutate(`Age Response` = factor(`Age Response`, levels  = c("18-29","30-44","45-60","> 60"))) %>%
  ggplot(aes(x = `Age Response`))+
  geom_bar(aes(y = prop))

Error in layer(data = data, mapping = mapping, stat = stat, geom = GeomBar, : object 'prop' not found

我们可以在

geom\u栏中添加
stat='identity'
：

library(dplyr)
library(ggplot2)

starwars_age %>%
  mutate(`Age Response` = factor(`Age Response`, 
                          levels  = c("18-29","30-44","45-60","> 60"))) %>%
  ggplot(aes(x = `Age Response`)) + 
  geom_bar(aes(y = prop), stat = 'identity')

您想要几何图形条（aes（y=prop），stat='identity'）

吗？是的，这就行了！非常感谢。
