Geom_line失败:参数隐含不同的行数
Geom_line失败:参数隐含不同的行数
提问于 2018-02-12 14:12:16
我正试图在我的条形图中添加一个“重要性条”，就像这里展示的那样：https://stackoverflow.com/a/29263992/9188785。
但是，当我尝试在我的数据上重新生成它时，我得到了以下错误：... arguments imply differing number of rows: 6, 0。
请注意，只要我在末尾不包含geom_line，一切都可以正常工作。

您必须将fill从主ggplot()函数迁移到geom_bar，因为fill美学不适用于geom_line。
# Using dummy sd as not specified
sd <- 10
library(ggplot2)
ggplot(df, aes(cat, means)) +
geom_bar(aes(fill = cat), stat = "Identity", width = 0.75) +
geom_errorbar(aes(ymin = means - sd, ymax = means + sd),
width = 0.2, position = position_dodge(0.9)) +
geom_line(data = df1, aes(a, b)) +
annotate("text", x = 2, y = 350, label = "*", size = 8) +
scale_fill_grey(start = 0.4, end = 0.8) +
labs(y = "Mean",
fill = NULL) +
theme(legend.position = "none",
axis.text.y = element_text(family = "Arial",size=14,face = "bold"),
axis.text.x = element_text(family = "Arial", size = 16, face = "bold"),
axis.title.x = element_blank(),
axis.title.y = element_text(family = "Arial",size = 16, face = "bold"))
