如何根据不同的分位数更改geom_quantile中的线型？

问题描述

我想根据分位数将 geom_quantile 中的线型更改为不同的线型。添加 linetype =“” 会将相同的线型应用于不同的分位数。相反，我想用.5实线，.3和.7的虚线以及.05和.95的虚线。

这是数据集的一部分：

df_long <- structure(list(year = c(1993,1994,1995,1996,1997,1993,1997),value = c(-0.0738688893838062,0.163757217900673,0.0857009807383771,-0.0667526720322341,0.0887060256107777,-0.0705604326484671,-0.034097173504119,0.111527592192091,-0.0457480764982465,-0.021583994766979,0.0315272708167682,0.0677257599658057,0.201360838487842,-0.0439384872883349,0.0352108660145989,0.00290602695874642,-0.0191047098517949,0.154388472709404,-0.0551628136705012,-0.0116829416335616,-0.00631796777141269,0.128820227737596,-0.0804450935804719,-0.0177009372848825,-0.0083312825335341,-0.0823085797209683,-0.0123399865315431,0.222205920508411,-0.0242032678683269,-0.0170395037335201,-0.106064297340727,0.0347329264648886,0.074020242269053,-0.00572727991816724,0.0210114931568262,-0.288679652994857,-0.0275640444206321,0.0299901988583031,0.298443737803506,0.0658031220317905,0.0682685773016796,0.18732469463018,0.088955508320856,0.0530846554927398,-0.736970343793129,0.111899139738996,-0.0133243118307523,-0.00943611596382643,-0.0387819600157773,3.35423479236764,-0.502363908141791,0.0511261883422458,0.0329065085527587,-0.0957237477272243,0.0219330316850432,-0.103146077645506,-0.0900595090357357,0.0143041336251402,-0.196830556041808,0.15006983964848,-0.199215590911409,-0.391178850934326,-0.309466944847281,-0.210074148976359,0.0621269708298122,-0.141795064523149,0.186715408723252,-0.0932781215854355,-0.252274661523447,0.0311615049862106,-0.118714420708426,0.196978608015062,0.0446075502804535,-0.183006199496033,0.320569582819935,-0.281136431971191,0.121160211180941,-0.124283126420151,-0.285441899579401,0.201538081023234,0.333489583806246,0.0489425412386162,-0.15396195544482,0.0904023603879698,-0.0620362904872416,0.154384885949913,0.00766253819373763,0.147310771448641,-0.0824091765728805,0.116736781380315,0.0797858883570994,0.445226197369783,-0.614739223178009,0.103806438257921,-0.130146811666976,-0.438085244089705,0.272598467933602,0.0179854969797342,-0.211999005594562,0.198933665513538)),row.names = c(NA,-100L),class = c("tbl_df","tbl","data.frame"))

我不知道如何在以下代码中指定它：

    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 ..）））给了我五行不同的内容，如下图所示。

我怎么只能得到上面指定的3种不同类型的线？

解决方法

请发布您的数据（使用dput函数），以便我们运行代码。但是我可以猜到您正在寻找的是在您的geom_quantile中添加这种美感：

aes(linetype = factor(..quantile..))

要手动设置线型的值，您可以执行以下操作：

scale_linetype_manual(values=c("dotted","dashed","solid","dotted"))

请注意，您按照定义quantiles的顺序进行设置。输出（图例）：

要更改图例以不重复线型：

scale_linetype_manual(breaks=c(.05,.3,.5),labels=c("0.05 or .95","0.3 or 0.7","0.5"),values=c("dotted","dotted"))

输出（旧版）：

糟糕：您可以通过添加name="whatever"来更改图例的名称。
