There's no command or function that specifically targets this operation, but it's fairly simple to re-order the series in a dataset via lists -- which can be treated as vectors (of series ID numbers) for manipulation -- plus the "store" and "open" commands. Here's an example. Suppose we want to move the COLLEGE series from ID 9 to ID 2 in Ramanathan dataset 4-10: <hansl> open data4-10 list L = dataset newpos = 2 oldpos = varnum(COLLEGE) matrix mL = L tmp = mL[newpos] mL[newpos] = oldpos mL[oldpos] = tmp L = mL store reordered.gdt L open reordered.gdt </hansl> Allin _______________________________________________ Gretl-users mailing list -- gretl-users(a)gretlml.univpm.it To unsubscribe send an email to gretl-users-leave(a)gretlml.univpm.it Website: https://gretlml.univpm.it/postorius/lists/gretl-users.gretlml.univpm.it/
