我需要在ggplot上方的标签上方放置标签.我曾经使用找到的方法(这里),但这似乎不再工作,因为我的ggplot2更新,因为我现在收到错误消息:

Error in continuous_scale(c("y", "ymin", "ymax", "yend", "yintercept",  : 
  unused argument(s) (formatter = "percent")

使用示例时,如何再次在条形图上方绘制数值:

df <- structure(list(A = structure(c(1L, 1L, 1L, 2L, 2L, 2L, 3L, 3L,
3L), .Label = c("0-50,000", "50,001-250,000", "250,001-Over"), class = "factor"),
    B = structure(c(1L, 2L, 3L, 1L, 2L, 3L, 1L, 2L, 3L), .Label = c("0-50,000",
    "50,001-250,000", "250,001-Over"), class = "factor"), Freq = c(0.507713884992987,
    0.258064516129032, 0.23422159887798, 0.168539325842697, 0.525280898876405,
    0.306179775280899, 0.160958904109589, 0.243150684931507,
    0.595890410958904)), .Names = c("A", "B", "Freq"), class = "data.frame", row.names = c(NA,
-9L)) …
