如何在R中对行矩阵进行箱图绘制? [英] How to boxplot row-wise matrix in R?

问题描述

我有一个8列的matrix.对于每一行，我想绘制一个箱形图.我更喜欢将箱线图放在一个图中.因此，以下示例应在单个图像中产生4个箱形图(每个8个值).

I have a matrix with 8 columns. For each row I'd like to a plot a single boxplot. I prefer the boxplots to be in a single plot. So the following example should produce 4 boxplots (8 values each) - all in a single image.

数据示例:

> data[2:5,]
     [,1] [,2] [,3]      [,4]      [,5]      [,6]      [,7]      [,8]     
[1,] 0.6  0.5  0.5357143 0.5357143 0.5357143 0.5357143 0.5357143 0.5185185
[2,] 0.5  0.5  0.5357143 2.5357143 0.5357143 0.5357143 0.5357143 0.5185185
[3,] 0.5  0.7  0.5357143 0.5357143 0.5357143 0.5357143 0.5357143 0.5185185
[4,] 0.5  0.5  1.5357143 0.5357143 0.5357143 0.5357143 0.5357143 0.5185185

到目前为止，我已经尝试过:

So far I've tried:

> boxplot(data[2:5,])
Error in sort.int(x, na.last = na.last, decreasing = decreasing, ...) : 
  'x' must be atomic

和这篇SO帖子:

> boxplot(as.list(as.data.frame(data[2:5,])))
Error in sort.int(x, na.last = na.last, decreasing = decreasing, ...) : 
   'x' must be atomic

我已经奋斗了很久了.你能给我提示吗?

I've been struggling for ages. Could you please give me hint?

> dput(data[2:5,])
structure(list(0.5, 0.5, 0.5, 0.5, 0.5, 0.5, 0.5, 0.5, 0.535714285714286, 
    0.535714285714286, 0.535714285714286, 0.535714285714286, 
    0.535714285714286, 0.535714285714286, 0.535714285714286, 
    0.535714285714286, 0.535714285714286, 0.535714285714286, 
    0.535714285714286, 0.535714285714286, 0.535714285714286, 
    0.535714285714286, 0.535714285714286, 0.535714285714286, 
    0.535714285714286, 0.535714285714286, 0.535714285714286, 
    0.535714285714286, 0.518518518518518, 0.518518518518518, 
    0.518518518518518, 0.518518518518518), .Dim = c(4L, 8L))

推荐答案

要从矩阵中绘制箱线图，我们可以使用boxplot.matrix函数:

To draw boxplots out of matrices, we can use the boxplot.matrix function:

boxplot.matrix(data, use.cols = FALSE)
