  x = NULL,
  pattern = NULL,
  date_format = "%Y-%m-%d",
  indice_level = "year",
  week_start = getOption("lubridate.week.start", 1)
)

Arguments

x	SpatRaster or a vector of dates, from which to extract the dates of the time-series.
pattern	string or characters to remove from the date name (e.g. remove the character "X" from "X2001.07.15"), default is null.
