所以我尝试使用 tikzDevice 来获取矢量图形，然后我想将其包含在我的 Overleaf 文件中。但是，当我使用此处的指令时，我遇到了问题。

另外，我使用 RStudio 版本 1.3.929 和最新的 MikTex。我还更新了所有软件包。

# Example by Ilyass

library(tikzDevice)
library(ggplot2)
    
options(tz="Europe/Berlin")

#Dummy data for the plot
y <- exp(seq(1,10,.1))
x <- 1:length(y)
data <- data.frame(x = x, y = y)

#Create a .tex file that will contain your plot as vectors
tikz(file = "plot_test.tex", width = 5, height = 5)

#Simple plot of the dummy data using LaTeX elements
    plot <- ggplot(data, aes(x = x, y = y)) + 
        geom_line() +
        ggtitle( paste("Fancy \\LaTeX ", "\\hspace{0.01cm} title")) +
        labs( x = "$x$ = Time", y = "$\\Phi$ = Innovation output") +
        theme_bw()

#This line is only necessary if you want to preview the plot right after compiling
print(plot)

#Necessary to close or the tikxDevice .tex file will not be written
dev.off()

如果我运行我的代码（见上文），我会收到错误消息：

TeX 无法计算以下指标：\char77

然后我运行它并收到此错误消息：

!  ==> Fatal error occurred, no output PDF file produced!

我可以通过使用以下命令在正确的位置设置 pdflatex 来解决这个问题。

getOption("tikzLatex")
options("tikzLatex"='/usr/bin/pdflatex')

但是，不，我得到一个全新的错误，我找不到任何帮助。

Error in system(latexCmd, intern = TRUE, ignore.stderr = TRUE) : error in running command

有谁知道我该如何解决这个问题或 tikzDevice 的替代方案？
