使用 Tikz 的新 R 徽标

我想R用 制作以下新标志 tikz。

在此处输入图片描述

我的 MWE 输出为：

\documentclass{standalone}
\usepackage{tikz}
\begin{document}

\begin{tikzpicture}[]

\node[blue] at (0,0)  {R};
\draw (0,0) ellipse (28pt and 20pt);
\draw (0,0) ellipse (18pt and 14pt);

\end{tikzpicture}

\end{document}

在此处输入图片描述

我的输出与期望结果不太接近。任何这方面的帮助都将不胜感激。谢谢

最好的办法是从 Inkscape 导出所有内容，但在这里我仅导出了 R 字母，并通过旧徽标颜色将其放置在省略号上。您可能需要适当调整它，我只是在这里进行近似。

\documentclass[tikz]{standalone}
\definecolor{rlogo}{RGB}{126,142,176}    
\begin{document}
\begin{tikzpicture}
\shade[even odd rule,shading angle=-110] (0,0) ellipse [x radius=3,y radius=2] (0.4,-0.1) ellipse [x radius=2.4,y radius=1.5];

带有 TikZ 的 R 符号

答案3

我无法在新版本的 inkscape 上重新安装 svg2tikz 插件，但在 ubuntu 的命令行中，可以运行：

wget https://upload.wikimedia.org/wikipedia/commons/1/1b/R_logo.svg
pip install git+git://github.com/aloisklink/svg2tikz --user
svg2tikz --figonly R_logo.svg

第一行下载 R 徽标的 svg，第二行安装 svg2tikz python 库，第三行将 svg 文件导出到 tikz。注意，我安装的是原始 svg2tikz 的一个分支

你得到：

虽然不是非常好，但可以作为起点。
