刪除雙條圖中的特定條

Question

我試圖刪除我的情節中第二排面板上多餘的「專業/復古」標籤。但是，我仍然希望保持最上面的面板標籤不變。我已經嘗試了過去一小時，有選擇地刪除第二排面板上的第一條，我想知道這裏有沒有人知道如何做到這一點。請參閱下面的技術細節。

我有以下情節：

它從以下數據中生成：

    "Measure", "Location", "JudgementType", "Accuracy", "LL", "UL" 
    ), row.names = c(NA, -56L), class = "data.frame") 

我把它用用下面的代碼可視化：

library(ggplot2) 

p1 <- ggplot(data = absBtwnDat, aes(x = as.numeric(as.character(setSize)), 
            y = Accuracy, group = Measure, 
            colour = Measure))+ 
    geom_point()+ 
    geom_line(aes(linetype = Measure))+ 
    scale_x_continuous("Trial Set Size", breaks = 2:8)+ 
    scale_y_continuous("Accuracy (# Correct)", breaks = 0:8, limits = c(0, 8))+ 
    geom_errorbar(aes(ymin = LL, ymax = UL), width = .1, size = .75)+ 
    scale_colour_grey(start = .8, end = .4)+ 
    facet_wrap(~JudgementType+Location, dir = "v")+ 
    theme(legend.position = "top") 

只是爲了確定，我已經突出了不想要的條下面的圖片：

Answer 1

有了這個你只有每個面板標籤的一列，但他們仍然包括話。

p1 <- ggplot(data = absBtwnDat, 
     aes(x = as.numeric(as.character(setSize)), y = Accuracy, 
      group = Measure, 
      colour = Measure))+ 
    geom_point()+ 
    geom_line(aes(linetype = Measure))+ 
    scale_x_continuous("Trial Set Size", breaks = 2:8)+ 
    scale_y_continuous("Accuracy (# Correct)", 
       breaks = 0:8, limits = c(0, 8))+ 
    geom_errorbar(aes(ymin = LL, ymax = UL), 
      width = .1, size = .75)+ 
    scale_colour_grey(start = .8, end = .4)+ 
    facet_wrap(~JudgementType + Location, 
     dir = "v", 
     labeller = label_wrap_gen(multi_line=FALSE)) + 
    theme(legend.position = "top") 
    p1 

Answer 2

這裏是一個可能的解決方案：

g1 <- ggplotGrob(p1) 
k <- which(g1$layout$name=="strip-t-1-2") 
g1$grobs[[k]]$grobs[[1]]$children[[2]]$children[[1]]$label <- "" 
g1$grobs[[k]]$grobs[[1]]$children[[1]]$gp$fill <- NA 

k <- which(g1$layout$name=="strip-t-2-2") 
g1$grobs[[k]]$grobs[[1]]$children[[2]]$children[[1]]$label <- "" 
g1$grobs[[k]]$grobs[[1]]$children[[1]]$gp$fill <- NA 

library(grid) 
grid.draw(g1)
