weeks: Show ceiling / floor days of a week

In tjebo/tjebtools: My utilities

Usage

week_floor(x, weekend = NULL)

Arguments

x	Vector of dates
weekend	what's the end of week? Default to Sunday

Value

vector of dates. can be used in aggregations, e.g. with zoo.aggregate

Weekend

weekday names in locale (!!) If you want to pass in a different locale, use index instead. Also accepts index 0:6 (d0 = Sunday, d1 = Monday,..., d6 = Saturday)
