R 和 RStudio 不显示希腊字母和其他符号 - 而是显示方块 [英] R and RStudio don't display greek letters and other symbols - display squares instead

问题描述

我似乎无法在 r 中显示希腊字母.我正在使用 RStudio，无论我尝试什么，我似乎都无法显示希腊字符.最初，我尝试在 bquote 中显示希腊字母，使用的是我所学的课程中的语法，即 prof.发表并证明它在课堂上有效.当它显示的只是正方形**时，我尝试了更基本的希腊字母显示方式.我尝试使用 expression 然后我试图找到最简单的方法并运行我在网上找到的这个语法:

I can't seem to display greek letters in r. I'm working with RStudio, and I can't seem to display greek characters no matter what I try. Initially I tried to display greek letters inside bquote, using syntax from a class I took, which the prof. published and demonstrated it worked in class. When all it showed was squares**, I tried more basic ways of displaying greek letters. I tried to use expression and than I tried to find the simplest way and ran this syntax which I found online:

mycoef <- rnorm (1000)
hist(mycoef, main = expression(beta))

在所有情况下，它要么显示一个正方形(如无法识别的符号)，要么只显示单词(beta、chi 等).此语法还使用 R 而不是 RStudio 显示一个正方形.
我试图稍微改变文件的编码(ASCII/UTF-8)，但这并没有改变任何东西.如果有任何改变，我正在使用 Mac(macOS Sierra 10.12.4).

In all cases it either display a square (like an unrecognized symbol), or just the word (beta, c etc.,). This syntax also displayed a square using R instead of RStudio.
I tried to change a bit the encoding of the file (ASCII/UTF-8), but this didn't change anything. I am working on a mac (macOS Sierra 10.12.4) if that changes anything.

**当使用 bquote 语法时，希腊字母并不是它变成正方形的唯一字符.没有引号的 == 和 ~~ 也显示为正方形.

**when using the bquote syntax, greek letters were not the only characters it changed to squares. Also == and ~~ without quotes were displayed as squares.

请注意，为了解决此问题，我运行了 sessionInfo 中显示的此语法 - Sys.setlocale("LC_ALL", "pt_PT.ISO8859-1")，但没有帮助.

Note that as a try to fix this problem I ran this syntax that is displayed in the sessionInfo - Sys.setlocale("LC_ALL", "pt_PT.ISO8859-1"), which didn't help.

谢谢！

推荐答案

我在 Windows 上更新符号字体解决了这个问题.(1) 下载Symbol.ttf文件(https://www.fontsupply.com/fonts/S/Symbol.html),(2) 在您的\Windows\Fonts 文件夹中找到文件symbol.ttf，并替换为新副本.

I solved this problem updating the Symbols Font on Windows. (1) Download the file Symbol.ttf (https://www.fontsupply.com/fonts/S/Symbol.html), (2) Find the file symbol.ttf in your \Windows\Fonts folder, and replace with the fresh copy.
