打印漂亮的data.frames / tables到控制台 [英] Print pretty data.frames/tables to console

问题描述

有没有办法以更易读的方式将小的 data.frames 打印到控制台？

Is there a way to print small data.frames to the console in a more readable manner?

例如，是否可以输出到控制台：

For example, would it be possible to output to the console:

library(MASS)   
iris[1:5, ]

  Sepal.Length Sepal.Width Petal.Length Petal.Width Species
1          5.1         3.5          1.4         0.2  setosa
2          4.9         3.0          1.4         0.2  setosa
3          4.7         3.2          1.3         0.2  setosa
4          4.6         3.1          1.5         0.2  setosa
5          5.0         3.6          1.4         0.2  setosa

as

iris[1:5, ]

  +--------------+-------------+--------------+-------------+---------+
  | Sepal.Length | Sepal.Width | Petal.Length | Petal.Width | Species |
  +--------------+-------------+--------------+-------------+---------+
1 |          5.1 |         3.5 |          1.4 |         0.2 |  setosa |
2 |          4.9 |         3.0 |          1.4 |         0.2 |  setosa |
3 |          4.7 |         3.2 |          1.3 |         0.2 |  setosa |
4 |          4.6 |         3.1 |          1.5 |         0.2 |  setosa |
5 |          5.0 |         3.6 |          1.4 |         0.2 |  setosa |
  +--------------+-------------+--------------+-------------+---------+

我意识到对于大型 data.frames 来说，这会花费不必要的时间，但是如果可以选择的话，我希望能够查看更结构化的方式。

I realise for large data.frames it would take up an unnecessary amount of time, but if it's an option, I would like to be able to look at small frames in a more structured manner.

特别是，当我两个文本字段彼此相邻时，用两个字段之间的管道将它们分开会更容易，因为单词之间的间距

In particular, when I have two text fields next to each other, it would be much easier with a pipe between the two fields to separate them, as the spacing between words is the same size as the spacing between columns.

谢谢

推荐答案

以防万一，任何人，我偶然发现了针织衫的 kable 可以得到漂亮印刷的事实。结合上面的 .Rprofile 建议，这似乎可以实现我的初衷。

In case it helps anyone, I just stumbled across the fact that knitr's kable achieves a nice pretty print. Combine with some of the .Rprofile suggestions above, this seems to achieve what I had in mind.

> knitr::kable(head(iris))

|------------:|-----------:|------------:|-----------:|:-------|
|          5.1|         3.5|          1.4|         0.2|setosa  |
|          4.9|         3.0|          1.4|         0.2|setosa  |
|          4.7|         3.2|          1.3|         0.2|setosa  |
|          4.6|         3.1|          1.5|         0.2|setosa  |
