Dates can be fussy. (Especially when they come to you mangled by manual formatting in spreadsheets.)
Sometimes it’s easier, when there are consecutive dates, simply to create them with seq
. For ts
, don’t even bother, just use object <- ts(source, start = c(2018,1 ) ...)
The date
can be unpacked multiple ways to make presentation easier. Here’s what can be done with days of the week.
suppressPackageStartupMessages(library(lubridate))
seq(c(ISOdate(2020,7,19)), by = "day", length.out = 7) -> the_days
wday(the_days)
## [1] 1 2 3 4 5 6 7
wday(the_days, label = TRUE)
## [1] Sun Mon Tue Wed Thu Fri Sat
## Levels: Sun < Mon < Tue < Wed < Thu < Fri < Sat
wday(the_days, label = TRUE, abbr = FALSE)
## [1] Sunday Monday Tuesday Wednesday Thursday Friday Saturday
## 7 Levels: Sunday < Monday < Tuesday < Wednesday < Thursday < ... < Saturday
# locale argument is OS specific
wday(the_days, label = TRUE, abbr = FALSE, locale = "fr_FR.utf8")
## [1] dimanche lundi mardi mercredi jeudi vendredi samedi
## 7 Levels: dimanche < lundi < mardi < mercredi < jeudi < ... < samedi
