I have a data frame that reads

I want to order the rows by client ID and date and using a black-box forecasting method create the data fcst(client,date of forecast, date for which forecast applies).
Assume that I have a function that given a time series x(1),x(2),....x(k) will generate f(i,j) where f(i,j) = forecast j days ahead, given data till date i.
How can the forecast data be best stored and how would I go about the taks of processing all the clients and dates?

Thanks. I am planning to write my own univariate forecasting routine. My question is mostly concerned with separting out the time series by client, generating the forecasts and then putting everything back together into something like ClientID | forecast date| date forecast is for |forecast| actual
