从 R 数据帧生成 LaTeX 输出

问题描述

我在 Ubuntu 上运行 R v2.14.1.我正在编写一个脚本，它将生成一个数据框，它代表一个结果表.

I am running R v2.14.1 on Ubuntu. I am writing a script that will generate a data frame, which represents a table of results.

我想将此表"输出为 .tex 文件，以便创建学术出版物"质量表以供打印.我听说过 Sweave(并阅读了一些关于 Sweave 的概述文档)——所以我认为这是继续前进的方式.然而，话虽如此，我实际上并没有看到 Sweave 将数据帧输出为 tex 文件的示例——到目前为止，我看到的所有 Sweave 示例似乎都是人为的，而不是我可以构建的东西.

I would like to output this 'table' as a .tex file so that I can create an 'academic publication' quality table, for printing. I have heard of Sweave (and read some overview docs about Sweave) - so I think this is the way to proceeed. However having said that I have not actually seen an example where Sweave outputs a dataframe as a tex file - all of the Sweave examples I have seen so far, seem contrived and not something that I can build upon.

我可以遵循一些准则来从数据框中输出 tex 吗?另外，如果我直接从我的 R 脚本构建 TeX 字符串并将字符串保存到文件中，它会更简单(更直接)吗?(我不清楚 Sweave 提供了哪些手动"手动构建 TeX 字符串).

Are there some guidelines I can follow, to output tex from a dataframe? Also, will it be simpler (more straight forward), if I built the TeX string directly from my R script and saved the string to file? (It is not clear to me, what Sweave offers over and above manually building the TeX string 'manually').

推荐答案

xtable 包有一些关于如何生成表格的示例 - 请参阅小插图.当您编写一个块时，请确保将块设置为 <<results=tex>>.参见 Sweave 示例，例如 这个.

这就是我输出 data.frame 的方式.

This is how I would output a data.frame.

<<results=tex>>
    xtable(my.data.frame)

原始结果如下所示:
