【问题描述】：
我正在尝试通过 tikzDevice 包使用 R/ggplot2 生成 tikz 图。当我弄清楚如何在我的 docker 映像上安装 R 和 tinytex 时，我不得不经历许多错误，但我遇到了以下错误，这让我很困惑。
当我运行生成我的情节的代码时，这是我得到的错误：
Error in getMetricsFromLatex(TeXMetrics, verbose = verbose) :
TeX was unable to calculate metrics for:
\char77
Run the following commands for diagnosis:
tikzTest()
tikzTest("\\char77")
Common reasons for failure include:
* The string contains a character which is special to LaTeX unless
escaped properly, such as % or $.
* The string makes use of LaTeX commands provided by a package and
the tikzDevice was not told to load the package.
The TeX and log files used for the calculation can help diagnose the
problem. If these files are missing, rerun the plot and make sure to
keep the R session open.
TeX file: tikzStringWidthCalc.tex
Log file: tikzStringWidthCalc.log
Calls: <Anonymous> ... descentDetails.text -> grid.Call -> <Anonymous> -> getMetricsFromLatex
Execution halted
而tikzDevice::tikzTest()的输出如下：

如您所见，我使用的是 tinytex，但我已按照 tinytex documentation 中的说明安装了此设置的推荐软件包（即，我已经运行了 tlmgr install pgf preview xcolor）。
我已经阅读了所有可能找到的关于这个主题的帖子，但我没有找到。任何帮助我解决此问题的提示将不胜感激。
