r - R ggplot2の凡例の色でファセットのテキストに色を付ける

Question

サンプルのデータフレームがあります:

dput(データ)

structure(list(DAF = c(0.00704225, 0.00352113, 0.00352113, 0.028169, 
0.00352113, 0.00704225, 0.0105634, 0.00352113, 0.0105634, 0.00352113, 
0.00352113, 0.00352113, 0.0176056, 0.0140845, 0.00352113, 0.0140845, 
0.00352113, 0.0105634, 0.00352113, 0.00352113, 0.0140845, 0.00352113, 
0.084507, 0.00352113, 0.0669014, 0.00704225, 0.00352113, 0.00352113, 
0.00704225, 0.00352113, 0.00704225, 0.00352113, 0.00352113, 0.028169, 
0.00352113, 0.00704225, 0.0105634, 0.00352113, 0.0105634, 0.00352113, 
0.00352113, 0.00352113, 0.0176056, 0.0140845, 0.00352113, 0.0140845, 
0.00352113, 0.0105634, 0.00352113, 0.00352113, 0.0140845, 0.00352113, 
0.084507, 0.00352113, 0.0669014, 0.00704225, 0.00352113, 0.00352113, 
0.00704225, 0.00352113), TYPE = structure(c(2L, 2L, 2L, 2L, 2L, 
2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 
2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 1L, 1L, 1L, 1L, 1L, 1L, 1L, 
1L, 1L, 1L, 1L, 1L, 1L, 1L, 1L, 1L, 1L, 1L, 1L, 1L, 1L, 1L, 1L, 
1L, 1L, 1L, 1L, 1L, 1L, 1L), .Label = c("All SVs", "bDEL"), class = "factor"), 
Function = structure(c(2L, 2L, 2L, 1L, 2L, 2L, 2L, 2L, 2L, 
2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 1L, 
2L, 2L, 2L, 2L, 2L, 1L, 2L, 2L, 2L, 1L, 2L, 2L, 2L, 2L, 2L, 
2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 1L, 
2L, 2L, 2L, 2L, 2L, 1L), .Label = c("Genic", "Intergenic"
), class = "factor")), .Names = c("DAF", "TYPE", "Function"
), class = "data.frame", row.names = c(NA, -60L))

を使用してプロットしました」

p1<-ggplot(sv,aes(x=DAF,y=..density..,fill=Function))+geom_histogram(position="dodge",binwidth=0.02)+facet_wrap( ~ TYPE, scales = "free",ncol=2)

データフレームからの注釈付きテキスト:

> dput(dat)
structure(list(x = c(0.05, 0.05, 0.05, 0.05, 0.05, 0.05), y = c(20L, 
17L, 14L, 35L, 30L, 25L), labs = structure(c(3L, 4L, 6L, 1L, 
2L, 5L), .Label = c("mean=0.0173", "mean=0.0190", "mean=0.0415", 
"mean=0.0440", "p=0.0393", "p=1.47e-08"), class = "factor"), 
    TYPE = structure(c(1L, 1L, 1L, 2L, 2L, 2L), .Label = c("All SVs", 
    "bDEL"), class = "factor")), .Names = c("x", "y", "labs", 
"TYPE"), class = "data.frame", row.names = c(NA, -6L))


p2<-p1+geom_text(aes(x, y, label=labs),size=1,data=dat,inherit.aes = F)

次のプロットが得られます。

ただし、凡例の対応する色で各ファセット内のテキスト「mean = ...」に色を付ける必要があります。つまり、ファセットのすべての SV では、「平均 = 0.0415」は「遺伝子」色で、「平均 = 0.0440」は「遺伝子間」色である必要があります。
