Is the question how many weeks are from the startDate to each of the
dateRange dates? If so, then try this:
startDate <- as.Date("2008-06-01")
dateRange <- as.Date(c( "2008-10-01","2008-12-01"))
floor(as.numeric(dateRange - startDate) / 7)
or depending on what the week is supposed to be we might want ceiling
in place of floor or neither floor nor ceiling if we want fractional
weeks.
