I have a fints object called x1, containing a column of dates and one column of values. I want to extract the following dates:
However, I can't be sure that x1 actually contains data from 1995q1 to 2014q2. So I want to do the following:
If x1 covers a longer time period, then only extract 1995q1 - 2014q2. If x1 covers a shorter time period, then replace all the missing values by 0.
Any ideas? Thanks!
