r - rmarkdown - 呈现数据帧列表

问题描述

限时删除！！

是否可以将 Markdown 文档中的数据框列表呈现为单独的表格?

Is it possible to render a list of data frames in a markdown document as individual tables?

示例

给定代码块

```{r listOfDf}

library(knitr)

df <- data.frame(a=rnorm(10),b=rnorm(10),c=c(rep("a",5), rep("b",5)))
l_df <- split(df, df$c)

kable(l_df)

```

这个输出

但我想要更接近 R 控制台中给出的内容:

But I would like something closer to that given in the R console:

> l_df
$a
           a          b c
1  1.2869909 -0.3117932 a
2  1.4621792  1.2826924 a
3 -0.4274641  0.3335532 a
4  0.7882973 -1.1966702 a
5 -1.2086910  0.1549691 a

$b
            a         b c
6  -0.9460508 1.4679430 b
7   0.6580554 0.5806850 b
8  -0.7103335 2.6036176 b
9  -2.0110167 2.0488055 b
10  0.7691045 0.3652907 b

但这也被呈现为表格(因此使用了kable())

But that is also rendered as a table(s) (hence the use of kable())

我试过一个循环*

for(i in 1:length(l_df)){
  kable(l_df[i])
}

但这也不起作用(*但它确实适用于图形)

but that doesn't work either (*but it does work for graphs)

推荐答案

pander 包被创建为 将几乎所有 R 对象转换为 Markdown.例如:

The pander package was created to transform almost any R objects into markdown. E.g.:

> pander(l_df)


  * **a**:

    -------------------------
        a          b       c
    ---------- ---------- ---
    0.5853656  1.3888279   a

    -0.6172632 -0.5179708  a

    -0.3321862 -0.2400778  a

    -0.6503349 0.9474224   a

    0.9476588  0.2288404   a
    -------------------------

  * **b**:

    -------------------------------------
             a            b       c
    -------- ------------ ----------- ---
     **6**   -0.637650387 0.26547037   b

     **7**   0.233576764  -0.47811415  b

     **8**   -0.283486652 0.61113065   b

     **9**   -0.794994493 -0.08609191  b

     **10**  -0.004526202 0.36841059   b
    -------------------------------------
