R / ggplot:带facet_wrap的垂直条带文本

标签: r ggplot2 facet-wrap

我在R中使用ggplot用facet_wrap绘制几个条件。 我想把带有情节名称的条带放在右边的垂直轴上,而不是放在顶部。

这是一个例子:

library(ggplot2)
dat<- data.frame(name= rep(LETTERS[1:5], each= 4), value= rnorm(20), time= rep(1:5, 4))
gg<- ggplot(data= dat, aes(x= time, y= value)) +
    geom_point() +
    facet_wrap(~ name, ncol= 1)

enter image description here 这里的情节名称(A,B,C,D,E)位于顶部,我希望它们位于右侧,如下所示:

gg + facet_grid(name ~ .)

enter image description here

有一个简单的开关吗? (我没有使用facet_grid,因为我想使用nrow附带的ncolfacet_wrap选项。

谢谢!达里奥

为了将来参考,您现在可以strip.position="right"使用put them on the right side,例如:

library(ggplot2)
dat<- data.frame(name= rep(LETTERS[1:5], each= 4), value= rnorm(20), time= rep(1:5, 4))
gg<- ggplot(data= dat, aes(x= time, y= value)) +
    geom_point() +
    facet_wrap(~ name, ncol= 1, strip.position="right")

如果您愿意在小平面的左侧使用小平面标签,那么有一个简单的解决方案,其中y轴成为x轴,x轴成为y轴。

library(ggplot2)
library(gridExtra)
library(gridGraphics)

# standard plot, facet labels on top
ggplot(diamonds) + 
  aes(x = carat, y = price) + 
  geom_point() + 
  facet_wrap( ~ cut)

enter image description here

# Use the gridExtra and gridGraphics utilities to rotate the plot.
# This requires some modifications to the axes as well.  Note the use of 
# a negative carat in the aes() call, and text modifications with theme()
grid.newpage()
pushViewport(viewport(angle = 90))
grid.draw(ggplotGrob(

  ggplot(diamonds) + 
    aes(x = price, y = -carat) + 
    geom_point() + 
    facet_wrap( ~ cut) + 
    scale_y_continuous(name = "Carat", breaks = -seq(0, 5, by = 1), labels = seq(0, 5, by = 1)) + 
    theme(axis.text.y = element_text(angle = 270), 
          axis.title.y = element_text(angle = 270), 
          axis.text.x = element_text(angle = 270))
    ))

facet_wrap标签移动到旋转图形的右侧,旋转角度为-90。但是,这将在图上方具有有效的x轴。你需要处理代码,将y轴标签从“标准”图的左侧移动到右侧,然后按-90所示旋转。
