更改我的R环境语言(Ubuntu)

Question

以为例

> mean(eta)
# [1] NA
# Warning message:
# In mean.default(eta) : l'argomento non è numerico o logico: restituisco NA
> Sys.setenv(LANG = "en")
> mean(eta)
# [1] NA
# Warning message:
# In mean.default(eta) : l'argomento non è numerico o logico: restituisco NA

我的renviron文件，仍然不工作：

### etc/Renviron.  Generated from Renviron.in by configure.
###
### ${R_HOME}/etc/Renviron
###
### Record R system environment variables.
Sys.setenv(LANGUAGE='en')
R_PLATFORM=${R_PLATFORM-'i686-pc-linux-gnu'}
## Default printer paper size: first record if user set R_PAPERSIZE
R_PAPERSIZE_USER=${R_PAPERSIZE-'a4'}
R_PAPERSIZE=${R_PAPERSIZE-'letter'}
## Default print command
R_PRINTCMD=${R_PRINTCMD-'/usr/bin/lpr'}

我认为问题是：

Sys.getenv(LANG)
Errore in Sys.getenv(LANG) : oggetto "LANG" non trovato

还有：

Sys.getenv(LANGUAGE)
Errore in Sys.getenv(LANGUAGE) : oggetto "LANGUAGE" non trovato

还有：

还有另一件事：如果stackoverflow一直阻止我向其他人显示代码或控制台输出，我应该如何在这里显示R输出或代码？

Answer 1

请参阅help(Startup)——您必须在~/.Renviron中设置它，以便在主R进程开始之前设置它。

Answer 2

我解决这个问题的一种方法是安装Rstudio并在控制台上键入：

> Sys.setenv(LANGUAGE="en_US.utf8")
> 2+x
Error: object 'x' not found

仍然不知道为什么在Ubuntu终端上打字时这不起作用。
