在Rstudio中使用特殊字符 [英] Using special characters in Rstudio

问题描述

我正在使用Rstudio中的一些特殊字符.它把它们掩盖成普通的字母.

  print(Safarzyńska2013"​​)[1]"Safarzynska2013"x<-毛利人"X[1]毛利人" 

有什么方法可以读取确切的原始字符.以下信息可能会有所帮助:Rstudio的默认编码为UTF-8

  sessionInfo()R版本3.1.1(2014-07-10)平台:x86_64-w64-mingw32/x64(64位)语言环境:[1] LC_COLLATE =英语_美国.1252 LC_CTYPE =英语_美国.1252[3] LC_MONETARY =英语_美国.1252LC_NUMERIC = C[5] LC_TIME =英语_美国.1252附带的基本软件包:[1]统计图形grDevices utils数据集方法库通过名称空间(未附加)加载:[1] tools_3.1.1 

解决方案

这不是RStudio独有的问题.

在RGui控制台上键入

print(Safarzyńska2013"​​)还将其转换为纯字母.从RGui中以UTF-8编码的脚本运行此代码将返回 [1]"Safarzy?ska2013"​​ .

我认为在控制台上键入此类特殊字符不是一个好主意. x<-"SomeString";Encoding(x)返回"unknown" ，这可能是问题所在:R不知道您在控制台上使用哪种编码，并且可能没有机会获得原始编码./p>

我将Safarzyńska2013\nMāori\ n"放入以UTF-8编码的文本文件中.然后，以下方法可以正常工作:

  tbl<-read.table('c:/test1.txt'，编码='UTF-8'，stringsAsFactors = FALSE)tbl [1,1]tbl [2,1]Encoding(tbl [1,1])#返回"UTF-8" 

如果您确实要使用控制台，则可能必须掩盖特殊字符.在?Encoding 中，我们找到以下示例来创建带有特殊字符的单词:

  x<--"fa \ xE7ile"编码(x) 

实际上，我目前不知道如何获取特殊字符的这些代码，并且?Encoding 也没有任何提示...

I am working with some special characters in Rstudio. It coverts them into plain letters.

print("Safarzyńska2013")
[1] "Safarzynska2013"

x <- "Māori"
x
[1] "Maori"

Is there any way to read in the exact original characters. Following info might be helpful: Rstudio default encoding is UTF-8

解决方案

This not an exclusively RStudio problem.

Typing print("Safarzyńska2013") on the console of RGui also converts them to plain letters. Running this code from an UTF-8 encoded Script in RGui returns [1] "Safarzy?ska2013".

I don't think that it is a good idea to type such special chars on the console. x <- "SomeString"; Encoding(x) returns "unknown" and that is probably the problem: R has no idea what encoding you are using on the console and probably has no chance to get your original encoding.

I put "Safarzyńska2013\nMāori\n" in a text file encoded with UTF-8. Then the following works fine:

tbl <- read.table('c:/test1.txt', encoding = 'UTF-8', stringsAsFactors = FALSE)
tbl[1,1]
tbl[2,1]
Encoding(tbl[1,1])  # returns "UTF-8"

If you really want to use the console, you probably will have to mask the special chars. In ?Encoding we find the following example to create a word with special chars:

x <- "fa\xE7ile"
Encoding(x)

Actually I don't know at the moment how to get these codes for your special chars and ?Encoding has also no hints...
