  my.df<  -  data.frame（mean = c（ 0.045729661,0.030416531,0.043202944,0.025600973,0.040526913,0.046167044,0.029352414,0.021477789,0.027580529,0.017614864,0.020324659,0.027547972,0.0268722,0.030804717,0.021502093,0.008342398,0.02295506,0.022386184,0.030849534,0.017291356,0.030957321,0.01871551,0.016945678,0.014143042,0.026686185， 0.020877973,0.028612298,0.013227244,0.010710895,0.024460647,0.03704981,0.019832982,0.031858501,0.022194059,0.030575241,0.024632496,0.040815748,0.025595652,0.023839083,0.026474704,0.033000706,0.044125751,0.02714219,0.025724641,0.020767752,0.026480009,0.016794441,0.00709195），std.dev = c（0.007455271,0.006120299,0.008243454,0.005552582,0.006871527,0.008920899,0.007137174,0.00582671,0.007439398,0.005265133,0.006180637,0.008312494,0.006628951,0.005956211,0.008532386,0.00613411,0.005741645,0.005876588,0.006640122,0.005339993,0.008842722,0.006246828,0.005532832,0.005594483 ，0.007268493,0.006634795,0.0082870 31,0.00588119,0.004479003,0.006333063,0.00803285,0.006226441,0.009681048,0.006457784,0.006045368,0.006293256,0.008062195,0.00857954,0.008160441,0.006830088,0.008095485,0.006665062,0.007437581,0.008599525,0.008242957,0.006379928,0.007168385,0.004643819），parent.origin = c （ 父亲的， 父亲， 父亲， 父亲， 父亲， 父亲， 母体， ​​母体， ​​母体， ​​母体， ​​母体， ​​母体，父亲，‘父亲’，‘父亲’，‘父亲’，‘父亲’，‘父亲’，‘母亲’，‘母亲’，‘母亲’，‘母亲’，‘母亲’，‘母亲’，‘母亲’ 母体， ​​母体， ​​母体， ​​母体， ​​母体， ​​父亲， 父亲， 父亲， 父亲， 父亲， 父亲， 母体，母亲，母亲，母亲，母亲，父亲，父亲，父亲，父亲，父亲，父亲），组= c（F1r ：M  F1R：M， F1R：M， F1R：M， F1R：M， F1R：M， F1R：M， F1R：M， F1R：M ， F1R：M， F1R：M， F1R：M， F1R：F， F1R：F， F1R：F， F1R：F， F1R：F， F1R：F， F1R：F， F1R：F， F1R：F， F1R：F， F1R：F，F1R ：F  F1i：M， F1i：M， F1i：M， F1i：M， F1i：M， F1i：M， F1i：M， F1i：M ， F1i：M， F1i：M， F1i：M， F1i：M， F1i：F， F1i：F， F1i：F， F1i：F， F1i：F，F1i：F，F1i：F，F1i：F，F1i：F，F1i：F，F1i：F，F1i：F = c（1,2,3,4,5,6,1,2,3,4,5,6,1,2,3,4,5,6,1,2,3,4,5,6 ，1,2,3,4,5,6,1,2,3,4,5,6,1,2,3,4,5,6,1,2,3,4,5,6）） 
  

如下：

  library（ggplot2）
 
 p1 < -  ggplot（data = my.df，aes（factor（replicate），color = factor（parent.origin）））
1 p1 < -  p1 + geom_boxplot（aes（fill = factor（parent.origin），lower = mean-std.dev，upper = mean + std.dev，middle = mean，ymin = mean  -  3 * std.dev， ymax = mean + 3 * std.dev），position = position_dodge（width = 0），width = 0.5，alpha = 0.5，stat =identity）+ facet_wrap（〜group，ncol = 4）+ scale_fill_manual（values = c （红色，蓝色），标签= c（母亲，父亲），名称=父母等位基因）+ scale_colour_manual（值= c（红，蓝）， 母亲，父亲），名称=父母等位基因）
 p1 < -  p1 + theme（panel.grid.major = element_blank（），panel.grid.minor = element_blank（），panel.background = element_rect（fill ='white'，color ='white'），legend.position =none）+ theme（strip.background = element_rect（fill =white））
  

这给出：

我的问题是，如何在F1i：F，F1i：M，F1r：F，F1r：M分面标题中添加下划线（黑色），并使这些下划线的宽度为（）使用 annotate（）使用 >对于Inf和 x = -Inf <> $ 段并将 y / yend / code>， xend = Inf 。



  +注释（segment，x = Inf，xend = -Inf，y = Inf，yend = Inf，color =black，lwd = 1）
  

Let's say I want to plot my data:

my.df <- data.frame(mean = c(0.045729661,0.030416531,0.043202944,0.025600973,0.040526913,0.046167044,0.029352414,0.021477789,0.027580529,0.017614864,0.020324659,0.027547972,0.0268722,0.030804717,0.021502093,0.008342398,0.02295506,0.022386184,0.030849534,0.017291356,0.030957321,0.01871551,0.016945678,0.014143042,0.026686185,0.020877973,0.028612298,0.013227244,0.010710895,0.024460647,0.03704981,0.019832982,0.031858501,0.022194059,0.030575241,0.024632496,0.040815748,0.025595652,0.023839083,0.026474704,0.033000706,0.044125751,0.02714219,0.025724641,0.020767752,0.026480009,0.016794441,0.00709195), std.dev = c(0.007455271,0.006120299,0.008243454,0.005552582,0.006871527,0.008920899,0.007137174,0.00582671,0.007439398,0.005265133,0.006180637,0.008312494,0.006628951,0.005956211,0.008532386,0.00613411,0.005741645,0.005876588,0.006640122,0.005339993,0.008842722,0.006246828,0.005532832,0.005594483,0.007268493,0.006634795,0.008287031,0.00588119,0.004479003,0.006333063,0.00803285,0.006226441,0.009681048,0.006457784,0.006045368,0.006293256,0.008062195,0.00857954,0.008160441,0.006830088,0.008095485,0.006665062,0.007437581,0.008599525,0.008242957,0.006379928,0.007168385,0.004643819), parent.origin = c("paternal","paternal","paternal","paternal","paternal","paternal","maternal","maternal","maternal","maternal","maternal","maternal","paternal","paternal","paternal","paternal","paternal","paternal","maternal","maternal","maternal","maternal","maternal","maternal","maternal","maternal","maternal","maternal","maternal","maternal","paternal","paternal","paternal","paternal","paternal","paternal","maternal","maternal","maternal","maternal","maternal","maternal","paternal","paternal","paternal","paternal","paternal","paternal"), group = c("F1r:M","F1r:M","F1r:M","F1r:M","F1r:M","F1r:M","F1r:M","F1r:M","F1r:M","F1r:M","F1r:M","F1r:M","F1r:F","F1r:F","F1r:F","F1r:F","F1r:F","F1r:F","F1r:F","F1r:F","F1r:F","F1r:F","F1r:F","F1r:F","F1i:M","F1i:M","F1i:M","F1i:M","F1i:M","F1i:M","F1i:M","F1i:M","F1i:M","F1i:M","F1i:M","F1i:M","F1i:F","F1i:F","F1i:F","F1i:F","F1i:F","F1i:F","F1i:F","F1i:F","F1i:F","F1i:F","F1i:F","F1i:F"), replicate = c(1,2,3,4,5,6,1,2,3,4,5,6,1,2,3,4,5,6,1,2,3,4,5,6,1,2,3,4,5,6,1,2,3,4,5,6,1,2,3,4,5,6,1,2,3,4,5,6))

As follows:

library(ggplot2)

p1 <- ggplot(data = my.df, aes(factor(replicate), color = factor(parent.origin)))
p1 <- p1 + geom_boxplot(aes(fill = factor(parent.origin),lower = mean - std.dev, upper = mean + std.dev, middle = mean, ymin = mean - 3*std.dev, ymax = mean + 3*std.dev), position = position_dodge(width = 0), width = 0.5, alpha = 0.5, stat="identity") + facet_wrap(~group, ncol = 4)+scale_fill_manual(values = c("red","blue"),labels = c("maternal","paternal"),name = "parental allele")+scale_colour_manual(values = c("red","blue"),labels = c("maternal","paternal"),name = "parental allele")
p1 <- p1 + theme(panel.grid.major = element_blank(), panel.grid.minor = element_blank(), panel.background = element_rect(fill = 'white', colour = 'white'), legend.position = "none")+theme(strip.background=element_rect(fill="white"))

This gives:

My question is how can I add underlines (in black) to the "F1i:F","F1i:M","F1r:F","F1r:M" facet titles, and have the widths of these underlines be the same as the width of the facet?

解决方案

Use annotate() with geom segment and set y/yend values to Inf and x=-Inf, xend=Inf.

 + annotate("segment",x=Inf,xend=-Inf,y=Inf,yend=Inf,color="black",lwd=1)
