Convert date format YYWW to YYYY-MM-DD

Since the exact date isn't given in the input, this function will set the date to Monday of the week. As a precaution, a leading zero is added if it has been removed. This can e.g., happen if the input was "0107" and has been converted to a numeric 107. We need to export this function so that it can be found when using Arrow to process the data.

Usage

yyww_to_yyyymmdd(yyww)

Arguments

yyww

Character(s) of the format YYWW.

Value

Date(s) in the format YYYY-MM-DD.
