在RMarkdown中使用tikz graphdrawing库...需要使用lualatex引擎，但无法使其正常工作 [英] Using tikz graphdrawing library within RMarkdown ... Need to use lualatex engine, but can't get it to work
问题描述
我在rmd文件中有以下代码，该文件利用tikz来绘制图表:
I have the following code in an rmd file which leverages tikz for diagrams:
---
title: "TestNonTufteLua"
author: "Me"
output:
pdf_document :
latex_engine: lualatex
---
Prove tikz works:
```{r tikTest1, engine = "tikz"}
\usetikzlibrary{shapes}
\begin{tikzpicture}
\node[ellipse, draw=black, align = center] (Data) {Data $y_{n}$};
\end{tikzpicture}
```
Then, when you set `eval = TRUE` in the below code, it will not work.
```{r tikTest2, eval = FALSE, engine = "tikz"}
\usetikzlibrary{graphs, graphdrawing}
\usegdlibrary{layered}
\tikz [gr/.style={gray!50}, font=\bfseries]
\graph [layered layout] {
% A and F are horizontally aligned if you also set weight=0.5 for A -- C.
A -- [minimum layers=2] C -- F,
{ [nodes=gr, edges=gr] A -- B -- { E, D -- F } }
};
```
在第二个块中更改为eval=TRUE时，我得到以下内容
错误:
When changing to eval=TRUE in the second chunk, I get the following
error:
从第24-29行退出(testNonTufteLua.Rmd)错误:正在运行 '.\ tikz36747a021b22.tex'上的'texi2dvi'失败
Quitting from lines 24-29 (testNonTufteLua.Rmd) Error: running 'texi2dvi' on '.\tikz36747a021b22.tex' failed
LaTeX错误:rarygraphdrawing.code.tex:22:软件包pgf错误:您 需要运行LuaTeX才能使用图形绘图库.
LaTeX errors: rarygraphdrawing.code.tex:22: Package pgf Error: You need to run LuaTeX to use the graph drawing library.
使用RStudio中的knit按钮或使用render("testNonTufteLua.Rmd", output_format = pdf_document(keep_tex = TRUE, latex_engine = "lualatex")时，会发生此错误.我也尝试过将options(tikzDefaultEngine = "luatex")设置为使tikzDevice正确处理，但仍然无法正常工作.即使可以加载tikz-shapes库，我似乎也无法使graphdrawing库正常工作，而且该文档的其余部分似乎都是使用lualatex编译的.谢谢您的帮助！
This error occurs when using the knit button from RStudio or using render("testNonTufteLua.Rmd", output_format = pdf_document(keep_tex = TRUE, latex_engine = "lualatex"). I have also experimented with setting options(tikzDefaultEngine = "luatex") to get tikzDevice to handle it properly, but it still does not work. I just can't seem to get the graphdrawing library to work even though the tikz-shapes library can be loaded and also that the rest of the document seems to be compiled with lualatex. Thanks for any help!!
推荐答案
更新:同时knitr不再使用tools::texi2dvi，而是使用tinytex::latexmk.因此，必须在设置块中使用options(tinytex.engine = 'lualatex').
Update: Meanwhile knitr no longer uses tools::texi2dvi but tinytex::latexmk. One therefore has to use options(tinytex.engine = 'lualatex') in a set-up chunk.
这很棘手，因为您不是使用tikzDevice而是使用tikz引擎，该引擎使用tools::texi2dvi转换为PDF.您可以使用options(texi2dvi = "lualatex")进行更改.但是，默认模板不适用于LuaLaTeX.因此，我创建了一个修改后的模板:
This is rather tricky, since you are not using tikzDevice but the tikz engine, which uses tools::texi2dvi to convert to PDF. You can change this using options(texi2dvi = "lualatex"). However, the default template does not work with LuaLaTeX. I have therefore created a modified template:
\RequirePackage{luatex85}
\documentclass{article}
\usepackage[luatex,active,tightpage]{preview}
\usepackage{amsmath}
\usepackage{tikz}
\usetikzlibrary{matrix}
\begin{document}
\begin{preview}
%% TIKZ_CODE %%
\end{preview}
\end{document}
并使用engine.opts = list(template = "tikz2pdf.tex")指定该文件.将所有内容放到我的工作文件中:
And specify that file with engine.opts = list(template = "tikz2pdf.tex"). Putting it all together here my working file:
---
title: "TestNonTufteLua"
author: "Me"
output:
pdf_document :
latex_engine: lualatex
---
```{r}
options(texi2dvi = "lualatex")
```
```{r tikTest2, eval = TRUE, engine = "tikz", engine.opts = list(template = "tikz2pdf.tex")}
\usetikzlibrary{graphs, graphdrawing}
\usegdlibrary{layered}
\tikz [gr/.style={gray!50}, font=\bfseries]
\graph [layered layout] {
% A and F are horizontally aligned if you also set weight=0.5 for A -- C.
A -- [minimum layers=2] C -- F,
{ [nodes=gr, edges=gr] A -- B -- { E, D -- F } }
};
```
结果:
