如何重塑這些數據來繪製ggplot2的多行？

Question

我有一個數據幀，看起來像這樣：

lethal.y   lethal.x   resist.y   resist.x   mock.y   mock.x  
Min. :0.0000 Min. :0.0000 Min. :0.0000 Min. :0.0000 Min. :0.0000 Min. :0.0000 
1st Qu.:0.3724 1st Qu.:0.4349 1st Qu.:0.6580 1st Qu.:0.3102 1st Qu.:0.5065 1st Qu.:0.5143 
Median :0.6786 Median :0.8688 Median :0.9889 Median :0.6034 Median :0.9105 Median :0.9305 
Mean :0.5943 Mean :0.6961 Mean :0.8086 Mean :0.5645 Mean :0.7337 Mean :0.7445 
3rd Qu.:0.8229 3rd Qu.:0.9791 3rd Qu.:1.0000 3rd Qu.:0.8236 3rd Qu.:0.9863 3rd Qu.:0.9970 
Max. :1.0000 Max. :1.0000 Max. :1.0000 Max. :1.0000 Max. :1.0000 Max. :1.0000 

每個項目都有100行，而* .X和* .Y表示X，Y COORDS我想繪製每個這三個條件。

我想用ggplot2在不同顏色的線條上繪製這三個圖。我相信我需要融化（）數據幀到類似：

variable  x  y 
lethal  .05  .01 
lethal  .03  .02 
... 
resist 
... 
mock 

我只是不完全知道如何在這裏重塑數據。任何人都可以將我指向正確的方向嗎？謝謝！

按照要求，dput（頭（DF））

structure(list(lethal.y = c(1, 0.96880698743694, 0.943637604878407, 
0.927797183915007, 0.913304798925335, 0.898733226540142), lethal.x =

0.992162832558697, 0.9898151419445, 0.98845829511382), mock.x = c(0, 
0.0422315106004306, 0.0848393643462402, 0.127812802135558, 
0.17073684383134, 
0.212410640574118)), .Names = c("lethal.y", "lethal.x", "resist.y", 
"resist.x", "mock.y", "mock.x"), row.names = c(NA, 6L), class = 
"data.frame")

你實際上並沒有在這種情況下轉換數據。試試這個：

require(ggplot2) 

ggplot(df) + 
    geom_line(aes(x=lethal.x,y=lethal.y,col="lethal")) + 
    geom_line(aes(x=resist.x,y=resist.y,col="resist")) + 
    geom_line(aes(x=mock.x,y=mock.y,col="mock")) + 
    xlab("") + 
    ylab("") + 
    guides(col=guide_legend("Variable"))
