如何从R成功导出图并以pdf格式更改点大小？

I'm doing my manuscript plots using R. The journal require all the text, labels, numbeirng of the plots in 8 pt size. Reading, I found that using pdf() command, I can select the point size and the plot size too. However, the .pdf file is not generated and I got the error:

我正在使用R来做我的手稿图。该期刊需要8磅大小的所有文本，标签，数字。阅读，我发现使用pdf（）命令，我也可以选择点大小和绘图大小。但是，没有生成.pdf文件，我收到错误：

Error in pdf(file = "test.pdf", width = 5, height = 5, pointsize = 8) : cannot open file 'test.pdf'

pdf中的错误（file =“test.pdf”，width = 5，height = 5，pointsize = 8）：无法打开文件'test.pdf'

I think that I'm doing something wrong. How can I export the file succesfully?

我认为我做错了什么。如何成功导出文件？

pdf(
  file = "test.pdf",
  width = 5,
  height = 5,
  pointsize = 8
)
plot(1:10)
dev.off()

It sounds like an OS issue. Make sure a file test.pdf does not already exist or that you do not have it open. I was able to replicate the error only when I had the existing file opened.

这听起来像操作系统问题。确保文件test.pdf尚不存在或者您没有打开它。只有在打开现有文件时才能复制错误。

To avoid it in the future, I usually add datetime stamps to the end of my filenames.

为了避免将来出现这种情况，我通常会在文件名末尾添加日期时间戳。
