如何更改R的语言环境? [英] How to change the locale of R?

问题描述

我正在Ubuntu 12.10上使用R版本2.15.3(2013-03-01).系统是德语的，R也是如此.在搜索错误消息时，这很不方便.

I’m using R version 2.15.3 (2013-03-01) on Ubuntu 12.10. The System is in German and so is R. This comes unhandy when searching for error messages.

以这种方式在xterm中执行R $ LANG="C" R部分解决了该问题.然后，R用英语显示所有内容.但是，当以这种方式加载RStudio时，R解释器仍然是德语.因此，我正在寻找一种在R本身中更改R的语言环境的方法.

Executing R in xterm this way $ LANG="C" R partially solves the issue. Then R displays everything in English. But when loading RStudio this way, the R interpreter is still in German. So I’m looking for a way to change the locale of R in R itself.

我发现了这一点:如何在R中更改语言设置，但Sys.setenv(LANG = "en")对我不起作用:

I found this: How to change language settings in R, but Sys.setenv(LANG = "en") does’t work for me:

2+x
# Fehler: Objekt 'x' nicht gefunden
Sys.setenv(LANG = "en")
2+x
# Fehler: Objekt 'x' nicht gefunden

我也尝试了Sys.setenv(LANG = "en_US.UTF-8")，但没有成功.

I also tried Sys.setenv(LANG = "en_US.UTF-8") with no success.

Sys.getlocale()

Sys.getlocale()
# [1] "LC_CTYPE=de_DE.UTF-8;LC_NUMERIC=C;LC_TIME=de_DE.UTF-8;
# LC_COLLATE=de_DE.UTF-8;LC_MONETARY=de_DE.UTF-8;LC_MESSAGES=de_DE.UTF-8;
# LC_PAPER=C;LC_NAME=C;LC_ADDRESS=C;LC_TELEPHONE=C;LC_MEASUREMENT=de_DE.UTF-8;
# LC_IDENTIFICATION=C"

(为方便起见添加了行制动器)

(linebrakes added for convenience)

推荐答案

只是遇到了同样的问题，并找到了适用于Windows/Linux的解决方案:

Just had the same problem and found the solution that worked for me on Windows/Linux:

Sys.setlocale("LC_ALL","English")
