Re: [R] modifying list in loop

Hello, I don't understand your functions but neither of them returns a value. And in the loop that calls them for(period in 1:1){ BeginBal(Deal, period) } you don't assign the value of BeginBal to anything, so Deal is never updated. The corrected functions and a way of calling them would be

[R] Windowing Time Series in The Past

Dear All, I am sure the solution is a one liner, but I am a bit struggling. Given a time series which starts at a given time t_ini, I would like to set a initial start time farther away in the past and have NA before t_ini (I need this to align different time series). For instance

Hi R'ers: Attached, my R_code, the dataset, and my query. How can I delete column yhat AND STILL retain the order of Response? When I remove yhat, the resultant dataset has Response in the original order, not the reordered version I created. Any help is greatly accepted.
