Hi Alison, please have a look at the stack() function ("help stack") and also at "stack_data" package via: ... You need to stack your series which refer to some specific year. Section 4.5 of the gretl manual also deals with the 'stack' function. But in this case I don't think it's straightforward, Artur, it's not a case that is directly covered. At least that's how it seems to me. My suggested way until someone comes up with a better idea would be to split the file by column blocks such that each resulting new file would only contain a single variable (ROE, Var2, Var3, etc.). Once the individual variables have been read into gretl, merging them should not be a problem. cheers sven University of Northampton: Transforming Lives and Inspiring Change www.northampton.ac.uk This e-mail is private and may be confidential and is for the intended recipient only.
