我想更改geom_quantile中的线类型，以根据分位数具有不同类型的线。添加 linetype = "" 会将相同的线型应用于不同的分位数。相反，我希望用实线表示 0.5，用虚线表示 0.3 和 .7，用虚线表示 0.05 和 .95。
这是数据集的一部分:

我不知道如何在下面的代码中指定它:
ggplot(aes(x=year, y=value)) +
geom_jitter(size=3, alpha=0.35, width = .07) +
geom_quantile(quantiles = c(.05, .3, .5, .7, .95),
method = "rqss", lambda = .1,
colour = "red") +
xlab("Year") +
ylab("Percentage change") +
theme_minimal()
添加 (aes(linetype = Factor(..quantile..))) 会给出五条不同的线，如下图所示。
如何才能获得上面指定的 3 种不同类型的线路？
最佳答案
请发布您的数据(使用dput函数)，以便我们可以运行代码。但我可以猜测您正在寻找的是将这种美感添加到您的 geom_quantile 中:
aes(linetype = factor(..quantile..))
要手动设置线型值，您可以执行以下操作:
scale_linetype_manual(values=c("dotted", "dashed", "solid", "dashed", "dotted"))
请注意，您按照定义分位数的顺序设置它们。输出(图例):
要将图例更改为不重复线型:
scale_linetype_manual(breaks=c(.05, .3, .5), labels=c("0.05 or .95", "0.3 or 0.7", "0.5"),
values=c("dotted", "dashed", "solid", "dashed", "dotted"))
输出(图例):
观察:您可以通过添加 name="whatever" 来更改图例的名称。
