Time Series Objects/ MC Simulation
I am attempting to value convertible bonds through a Monte Carlo approach. I want to express call schedules as date-price tuples. Naturally, these tuples need to be expanded to match the frequency of the innovations in the MC process. 1. Is there a straigh-forward way to accomplish this "expansion"? 2. I have noted the existance of ts, its, zoo and fCalendar. Does anyone have an

Well, one can write a pair of loops, or write a single loop within which we calculate a vector at a time, but ... is there a "neat" way to do it? tiny example:
