在Mac OS X中的R包Cairo中设置系统字体 [英] Set system font in R package Cairo in Mac OS X

问题描述

由于在R的expression()命令中使用Unicode 引起的问题，我切换到Mac OS X上的R以创建一些图.但是，使用CairoPDF()，我在Windows中使用的选择字体的命令对Mac OS X无效，在Mac OS X上，输出.pdf文件始终使用Helvetica字体.

Because of the issue raised in Using Unicode inside R's expression() command, I am switching to R on Mac OS X to create some plots. Using CairoPDF(), however, the commands I use in Windows to select my fonts don't have any effect on Mac OS X, where the output .pdf file always has the Helvetica font.

library(package = "Cairo")
CairoPDF("test.pdf")
plot.new()
text(x=.5,y=.5,labels="\u0260",family="Times New Roman")
dev.off()

Windows中的输出为:

The output in Windows is:

Mac OS X中的输出为:

The output in Mac OS X is:

Times New Roman字体在两个系统上完全相同.

The Times New Roman font is exactly the same on both systems.

推荐答案

我是用CairoFonts而不是家庭论证来做到这一点的，这似乎被忽略了.

I did it with CairoFonts rather than the family argument, which seems to be getting ignored.
