...rent,by='1 week',length=53) Question: How to generate a sequence of past dates starting one week in the past relative to the current date. Obviously, what I wrote below is not correct. I think I can write a for loop and push each value into a vector. Is this the best way? Thanks. Satish past_dates = seq(current,by=-'1 week',length=156)

Hey, I need to get the number of years (as a number) between two dates. Here is what I have as a helper. # Returns the number of years between now and the specified date. def years_ago(date) dateDifference = DateTime.now - date results =Date.day_fraction_to_time(dateDifference) return results[0] / 24 / 365; end I''m sure there is a better way to do this. What is it?
