我有简单的RMarkdown文档:

---
output:
  word_document: default
  html_document: default
---


```{r,engine='tikz', fig.ext = 'png'}
\begin{tikzpicture}
\path (0,0) node
(x) {Hello World!}
(3,1) node[circle,draw](y) {$\int_1^2 x \mathrm d x$};
\draw[->,blue]
(x) -- (y);
\draw[->,red]
(x) -| node[near start,below] {label} (y);
\draw[->,orange] (x) .. controls +(up:1cm) and +(left:1cm) .. node[above,sloped] {label} (y);
\end{tikzpicture}
```

这是pgfmanual.pdf的17.11的例子.

如果我'png'改为'svg':HTML输出很棒

它用tikz引擎产生圆形和矩形.
但是,即使使用100%缩放,生成的图像在DOCX中看起来也很难看并且像素化:

我试图改变fig.width,dpi,out.width但没有得到积极的结果.

对我来说最好的结果将是以下内容:获取具有TikZ代码中指定尺寸的高分辨率图像.

是否可以提高从TikZ插入Word文档的图像的分辨率？

更新1:@CL使用set pandoc dpi使用pandoc_args的建议解决方案不起作用.

更新2:@tarleb解决方案提议{r,engine='tikz', engine.opts …

下面是我的实验 RMarkdown 文档（名为tikz-cyrillic.Rmd）：

---
title: "TikZ cyrillic test"
output:
  pdf_document:
    keep_tex: yes
    latex_engine: xelatex
    dev: tikz
  html_document: default
  word_document: default

```{r,engine='tikz', fig.ext = if (knitr:::is_latex_output()) 'pdf' else 'svg'}
\begin{tikzpicture}
\path (0,0) node
(x) {Hello World!}
(3,1) node[circle,draw](y) {$\int_1^2 x \mathrm d x$};
\draw[->,blue]
(x) -- (y);
\draw[->,red]
(x) -| node[near start,below] {???!} (y);
\draw[->,orange] (x) .. controls +(up:1cm) and +(left:1cm) .. node[above,sloped] {??????} (y);
\end{tikzpicture}
```

它基于pgfmanual.pdf 的 17.11 中的示例。

Gummi 使用TeXLive 和 XeTeX …

Below is the simplest Rmd file which I'm knitting to MS Word document using latest RStudio:

---
output:
  word_document: default
  bookdown::word_document2: default

```{sh, echo=FALSE, comment=''}
cat ~/latex-test.Rmd
```

The contents of ~/latex-test.Rmd are as follows:

Auto-numbered equation:

$$ f(x) = \sin(x) $$

LaTeX equation without label (using `\begin{equation}...\end{equation}`)

\begin{equation}
h(z) = \sinh(z)
\end{equation}

---

LaTeX equation with bookdown-supported label (using `\begin{equation}...(\#eq:label)\end{equation}`)

\begin{equation}
  f\left(k\right) = \binom{n}{k} p^k\left(1-p\right)^{n-k}
  (\#eq:binom)
\end{equation}

---

LaTeX equation with Xaringan-supported label (using `\begin{equation}...\label{label}\end{equation}`):

\begin{equation}
  g\left(k\right) …

在我的程序中,我需要计算总和:

.

我计算这个总和与新值2500倍C和z.

参数z可以是矢量.我编写了简单的for循环和矢量化版本代码,如下所示:

K = 200;
n_z = 40000;
C = ones(K,1); % an example, in real life the arey some coefficients (at next call will be new)
k = 0:K-1;
z = linspace(0, 2*pi, n_z); % at next call will be new

tic;
    my_sum_for = zeros(1, K);
    for i=1:n_z
       my_sum_for(i) = C' * tan(k' * z(i));
    end
toc; % Elapsed time is 1.820485 seconds.

tic;
     my_sum = C' * tan(k' * z); …
