在R中获取英语的工作日 [英] Get weekdays in English in R

问题描述

我在美国境外使用R，并且所有内容都可以用英语运行，但是weekdays()的结果仍然是西班牙语:

I am using R outside the US and I got everything working in English, but the result of weekdays() is still in Spanish:

Day <- seq(as.Date("2013-06-01"), by=1, len=30)
weekdays(Day)
[1] "sábado"    "domingo"   "lunes"     "martes"    "miércoles"  (...)

关于如何用英语获得工作日的任何想法吗?

Any ideas on how to get the weekdays in English?

推荐答案

Date和POSIX*t对象的打印似乎受LC_TIME语言环境类别控制.

Printing of Date and POSIX*t objects seems to be controlled by the LC_TIME locale category.

在Windows上，您可以这样更改:

On Windows, you change it like this:

## First, save the current value so we can restore it later
Sys.getlocale("LC_TIME")
# [1] "English_United States.1252"

## First in Spanish
Sys.setlocale("LC_TIME","Spanish Modern Sort")
# [1] "Spanish_Spain.1252"
weekdays(Sys.Date()+0:6)
# [1] "lunes"     "martes"    "miércoles" "jueves"    "viernes"   "sábado"   
# [7] "domingo"  

## Then back to (US) English
Sys.setlocale("LC_TIME","English United States")
# [1] "English_United States.1252"
weekdays(Sys.Date()+0:6)
# [1] "Monday"    "Tuesday"   "Wednesday" "Thursday"  "Friday"    "Saturday" 
# [7] "Sunday" 

在大多数* NIX上，等价于:

On most *NIXes, the equivalent would be:

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

特定的语言环境名称取决于操作系统，如?Sys.setlocale中所述.有关Windows接受的名称，请请参见此处.有关Linux接受的名称，请参见此处.

The particular locale names are OS-dependent, as mentioned in ?Sys.setlocale. For names accepted by Windows, see here. For names accepted by Linux, see here.
