我发现了这个,如何在带有ggplot2的R中将标签放在geom_bar上,但它只是将标签(数字)放在一个条上.

这就是说,每个x轴有两个条,怎么做同样的事情？

我的数据和代码如下所示:

dat <- read.table(text = "sample Types Number
sample1 A   3641
sample2 A   3119
sample1 B   15815
sample2 B   12334
sample1 C   2706
sample2 C   3147", header=TRUE)

library(ggplot2)
bar <- ggplot(data=dat, aes(x=Types, y=Number, fill=sample)) + 
  geom_bar(position = 'dodge') + geom_text(aes(label=Number))

然后,我们将得到:

似乎数字文本也定位在"闪避"模式中.我搜索了geom_text手册来查找一些信息,但无法使其正常工作.

建议？

我试图使标题不言自明,但这里 - 数据优先:

4L, 4L, 5L, 5L), .Label = c("vma", "vla", "ia", "fma", "fla"), class = "factor"), 
    ustanova = structure(c(1L, 2L, 1L, 2L, 1L, 2L, 1L, 2L, 1L, 
    2L), .Label = c("srednja škola", "fakultet"), class = "factor"),
