另存为PDF时，如何使用Latin Modern字体系列制作R图?

问题描述

如果我键入

  par(family ='CM Roman') 

然后我可以显示一个图，以Computer Modern字体显示.但是，当我尝试将其另存为PDF时，它会作为空白文档出现，这与我删除该行不同.

我如何才能将其正确保存为PDF?

此外，我该如何使用Latin Modern而不是Computer Modern?

解决方案

这是我在Windows中的操作方式:

1. 安装 extrafont 软件包.
2. 安装Latin Modern字体，例如来自

   If I type

   par(family='CM Roman')
   

   then I can get a plot to display with the Computer Modern font. However, when I try to save it as a PDF, it comes up as a blank document, unlike if I take out that line.

   How can I get it to save correctly as a PDF?

   Also, how can I use Latin Modern instead of Computer Modern?

   解决方案

   This is how I did it in Windows:

   1. Install the extrafont package.
   2. Install Latin Modern fonts, e.g. from http://www.fontsquirrel.com/fonts/latin-modern-roman. Watch out, you need to install the TTF version of the font, font_import() can't handle OTF.
   3. Import the fonts using font_import().
   4. Load the fonts using loadfonts(device = "win"). Use the device = "Win" parameter to make the preview in R Studio work.
   5. Set the font family graphics parameter using par(family = "LM Roman 10").
   6. Plotting in R Studio now works and so does pdf export (see the pictures below).

   This is the full code you need to use:

   # Run once
   install.packages("extrafont")
   library(extrafont)
   # Install **TTF** Latin Modern Roman fonts from www.fontsquirrel.com/fonts/latin-modern-roman
   # Import the newly installed LModern fonts, change the pattern according to the
   # filename of the lmodern ttf files in your fonts folder
   font_import(pattern = "lmroman*")
   
   
   # Run each time
   library(extrafont)
   loadfonts(device = "win")
   par(family = "LM Roman 10")
   x <- seq(1, 10, 1)
   y <- seq(1, 10, 1)
   plot(y ~ x, main="This plot uses LaTeX font!", ylab = expression(alpha))
