我在一段时间内设置工作日缩写的问题。我需要的是缩写“周一,周二,周三,周四,周五,周六,周日”。我使用的lubridate :: wday()函数给出了“Mon,Tue,Wed,Thu,Fri,Sat,Sun”的值。
“星期二”和“星期四”的日子差别很小。
x <- seq(Sys.Date() - 7, Sys.Date(), by = 1)
lubridate::wday(x, label = TRUE)
## [1] Thu Fri Sat Sun Mon Tue Wed Thu
我还使用语言环境更改了语言设置,但这并没有成功,因为我不确定要设置的可能参数(可能的选择)。
lubridate::wday(x, label = TRUE, locale = "French")
## [1] jeu\\. ven\\. sam\\. dim\\. lun\\. mar\\. mer\\. jeu\\.
lubridate::wday(x, label = TRUE, locale = "English")
## [1] Thu Fri Sat Sun Mon Tue Wed Thu
lubridate::wday(x, label = TRUE, locale = "English_Great Britain")
## [1] Thu Fri Sat Sun Mon Tue Wed Thu
lubridate::wday(x, label = TRUE, locale = "English_United States")
## [1] Thu Fri Sat Sun Mon Tue Wed Thu
差异可能来自我的R版本(现在3.4.2)的变化,因为有人提到这个新版本有关此主题的更改......(https://cran.r-project.org/bin/windows/base/NEWS.R-3.4.2.html - &gt; 在Sys.setlocale()中设置LC_ALL类别会使任何缓存的特定于语言环境的日/月名称和strptime()的AM / PM指示符无效(因为设置LC_TIME自R 3.1.0 以来)

由于您需要非标准缩写,因此您需要手动完成:
x <- seq(Sys.Date() - 7, Sys.Date(), by = 1)
Sys.setlocale("LC_TIME", "C") #since I'm at a non-English locale
factor(weekdays(x, TRUE),
levels = c("Mon", "Tue", "Wed", "Thu", "Fri", "Sat", "Sun"),
labels = c("Mon", "Tues", "Wed", "Thurs", "Fri", "Sat", "Sun"))
#[1] Thurs Fri Sat Sun Mon Tues Wed Thurs
#Levels: Mon Tues Wed Thurs Fri Sat Sun
我不确定你为什么认为这与R版本相关......
