Hello, I have two time series objects, 1 is yearly (population) and the other is quarterly (bankruptcy statistics). I would like to produce a quarterly time series object that consists of bankruptcy/population. Is there a pre-built function to intelligently divide these time series. The series I want is: br2001Q1/pop2001 , br2001Q2/pop2001, br2001Q3/pop2001, br2001Q4/pop2001, br2002Q1/pop2001, br2002Q2/pop2002, etc. This would not be too difficult to write but does anything like this already exist? -stephen [[alternative HTML version deleted]]
