R geom_bar 和 facet_grid 标签在条的顶部

Question

我正在努力使这张图看起来更好，但我受制于标签（在本例中为数字）。我怎样才能让他们显示在他们通讯栏的顶部？请注意它是 facet_grid。我有以下代码和输出：

ggplot(articles_europaoccidental_sex_count_unique_group, aes(Country, percentage)) + geom_bar(stat = "identity", position = "dodge", aes(fill=Gender)) + 
    facet_grid(~Propuesta) + geom_text(aes(label = round(percentage, 2)), position = position_dodge(width = 0.9), vjust = -1)

谢谢！

Answer 1

你快到了，只需要将 aes(fill=Gender) 移到 ggplot

里面

library(tidyverse)
#Reproducible data set
test_mtcars <- mtcars %>% group_by(cyl,am, gear) %>% summarise(mean = mean(mpg))

ggplot(test_mtcars, aes(as.factor(cyl), mean, fill=as.factor(am))) + geom_bar(stat = "identity", position = "dodge") + 
facet_grid(~gear) + geom_text(aes(label = round(mean, 2)), position = position_dodge(width = 0.9), vjust = -1)

R geom_bar 和 facet_grid 标签在条的顶部
