更改R的时间区域设置

Question

这是我的 sessionInfo()

R version 2.14.0 (2011-10-31)
Platform: i386-pc-mingw32/i386 (32-bit)

locale:
[1] LC_COLLATE=Chinese (Traditional)_Hong Kong S.A.R..950 
[2] LC_CTYPE=Chinese (Traditional)_Hong Kong S.A.R..950   
[3] LC_MONETARY=Chinese (Traditional)_Hong Kong S.A.R..950
[4] LC_NUMERIC=C                                          
[5] LC_TIME=Chinese (Traditional)_Hong Kong S.A.R..950    

attached base packages:
[1] stats     graphics  grDevices utils     datasets  methods   base     

loaded via a namespace (and not attached):
[1] tools_2.14.0

我尝试使用Sys.setlocale("LC_TIME", "en_US.UTF-8")转换输出日期,但它给了我这个错误:

> Sys.setlocale("LC_TIME", "en_US.UTF-8")
[1] ""
Warning message:
In Sys.setlocale("LC_TIME", "en_US.UTF-8") :
  OS reports request to set locale to "en_US.UTF-8" cannot be honored

我想知道为什么,我该怎么办？谢谢.

Answer 1

对于Windows:

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

Answer 2

Sys.setlocale("LC_TIME", "C")

似乎更安全,当"英语"产生"无法尊敬"警告时起作用.
