【R】Mac 中打开 R 后显示红色 Waring

打开 R 后显示红色 Waring :

During startup - Warning messages:
  1: Setting LC_CTYPE failed, using "C"
  2: Setting LC_COLLATE failed, using "C"
  3: Setting LC_TIME failed, using "C"
  4: Setting LC_MESSAGES failed, using "C"
  5: Setting LC_PAPER failed, using "C"
  [R.app GUI 1.50 (6126) x86_64-apple-darwin9.8.0]  
    WARNING: You are using a non-UTF8 locale, therefore only ASCII characters will work.  
    Please read R for Mac OS X FAQ (see Help) section 9 and adjust your system 
    preferences accordingly.  [History restored from /Users/mohammadgoodarzi/.Rapp.history]

处理方法:

首先在 R 中输入:

system("defaults write org.R-project.R force.LANG en_US.UTF-8")

然后在 系统终端中输入:

defaults write org.R-project.R force.LANG en_US.UTF-8

原因是系统 Shell 下的 locale 设置错误造成的,但是,你在 .bash_profile 或者 .bashrc 里设置 export LANGexport LC_ALL 都不是很管用
