set_week_start {aweek}

Get and set the global week_start variable

Description

This is a convenience wrapper around options() and getOption(), which allows users to input both numeric and character week start values

Usage

set_week_start(x = 1L)

get_week_start(w = NULL)

Arguments

x

a character or integer specifying the day of the week for conversion between dates and weeks.

w

if NULL, the global option "aweek.week_start" is returned. If w is an aweek object, then the "week_start" attribute is returned.

Value

for set_week_start, the old value of week_start is returned, invisibly. For get_week_start, the current value of week_start is returned.

# get the current definition of the week start
get_week_start() # defaults to Monday (1)
getOption("aweek.week_start", 1L) # identical to above

# set the week start
mon <- set_week_start("Sunday") # set week start to Sunday (7)
get_week_start()
print(set_week_start(mon)) # reset the default
get_week_start()

# Get the week_start of a specific aweek object.
w <- date2week("2019-05-04", week_start = "Sunday")
get_week_start(w)
