R 如何将ggplot2条形图的负x轴打断（标签）更改为正x轴打断（标签）？

我有一个数据框，看起来像这样：

df <- structure(list(gender = c("male", "male", "male", "female", "female", 
"female", "male", "male", "male", "male", "male", "female", "female", 
"female"), agegroup = c("-24", "25-34", "45-54", "-24", "25-34", 
"35-44", "-24", "25-34", "35-44", "65-", "unknown", "-24", "25-34", 
"35-44"), N = c(-2, -4, -1, 3, 4, 1, -3, -14, -1, -1, -2, 3, 
3, 1), N2 = c(2, 4, 1, 3, 4, 1, 3, 14, 1, 1, 2, 3, 3, 1), location = c("here", 
"here", "here", "here", "here", "here", "there", "there", "there", 
"there", "there", "there", "there", "there")), .Names = c("gender", 
"agegroup", "N", "N2", "location"), row.names = c(NA, 14L), class = "data.frame")

看来我是有意的。剩下的就是把-10和-5变回正数。有没有一种方法可以在不改变绘图外观的情况下执行此操作？

看起来您只需要将所有轴标签设置为正值，即取绝对值。我们可以使用

scale.*\u continuous

和

标签

参数来实现这一点。请注意，在这种情况下，我们需要变换y轴，因为我们必须在

coord_flip

之前参考该轴。

pretty

功能可用于方便地生成一些漂亮的轴打断：

将此添加到绘图中：

scale_y_continuous(breaks = pretty(df$N), labels = abs(pretty(df$N))

@阿克斯曼，谢谢！如果事先不知道会有哪些标签，有没有办法通过编程更改标签？@Axeman，如果你将此作为答案添加，我会接受。再次感谢！

scale_y_continuous(breaks = pretty(df$N), labels = abs(pretty(df$N))
