r - 未提供汇总函数，默认为 `mean_se()`

Question

我正在尝试使用一个函数将标准偏差误差条添加到我的 ggplot 条形图中。特别是，我想使用 mean_sdl。

ggplot(recall_info) +
 aes(x = Condition, y = pwords) +
  geom_bar(aes(Condition, pwords), position = "dodge", stat = "summary", fun.y = "mean") +
  stat_summary(fun.data = mean_sdl, width=0.05, geom = "errorbar") +
 labs(y = "% of words remembered", title = "Proportion of Words Remembered") +
 theme_light() + coord_cartesian(ylim=c(0,50)) + 
  geom_signif(comparisons = list(c("condition1", "condition2")), test = "t.test", map_signif_level=TRUE)

我收到以下错误:

No summary function supplied, defaulting to mean_se() Warning message: Ignoring unknown parameters: fun.y

我不明白出了什么问题。我在图表上得到的误差条显然是错误的——它们完全脱离了图表。

提前致谢。

Answer 1

只需更改

fun.y = "mean"

到

fun = mean
