Arguments

x

Vector of starting dates or items that can be converted to dates by todate.

y

Vector of ending dates or items that can be converted to dates by todate.

unit

Character indicating what to use as the unit of difference. Values like d, y, m or day, year, month will work. Takes just the first letter in lower-case to determine unit.

Convert to dates before running the difference. If you know your columns are already dates, setting to FALSE will make your code run faster.

do.numeric

Convert the output to a number instead of a date difference object.

Value

Vector of differences.
