R：ggplot2 - 開關參數不能按預期工作

有根據：http://docs.ggplot2.org/current/facet_grid.html

注：我已經與GGPLOT2的CRAN和Github的版本嘗試。

有了這個代碼，我應該期待這個圖：

data <- transform(mtcars, 
       am = factor(am, levels = 0:1, c("Automatic", "Manual")), 
       gear = factor(gear, levels = 3:5, labels = c("Three", "Four", "Five")) 
) 


p <- ggplot(data, aes(mpg, disp)) + geom_point() 
p + facet_grid(am ~ gear, switch = "both")

圖：

但我發現了一個類似的圖，其中「帶文本」是不是背後「axi」但在axi之前：
