There are a few new things in CVS (and the Windows snapshot) in response to points made by Ignacio a while back. Here we go: Databases in GUI: You can now select multiple series in a database window, using the usual shift and ctrl modifiers. Then the Display, Graph and Import menu items will work on all the selected series. Two things to note: (1) A multiple selection can only include series with a common frequency. (2) When multiple series are selected, the mechanism of dragging the series to the main gretl window doesn't work: this is a long-standing GTK bug. You have to use /Series/Import from the menu-bar or "Import" from the pop-up menu. There is also a new menu item, Delete, which deletes selected series from the database. This item is available only for native gretl databases to which the user has write access. [See note below for MS Windows.] Databases in CLI: The "delete" command now has a "--db" option, which allows you to delete specified series (given by name) from a native gretl database to which you have write access. You need to use the "open" command first, as in: open mydb.bin delete x15 y32 --db New "dataset" command: This subsumes the old commands "addobs" and "transpos", and adds options to compact or expand the dataset (i.e. lower or increase the data frequency) which were previously available only via the GUI menus. Please see the new help item for "dataset", but here's how it works by example: dataset addobs 24 dataset compact 1 dataset compact 4 sum dataset expand 12 dataset tranpose The command words "addobs" and "transpos" are still available as aliases, but they're gone from the manual and should be considered deprecated. [Note on Windows: It is extaordinarily difficult to find out if the current user has write access to a given file, involving calls to 5 win32 API functions with up to 8 arguments per function. I think I have this right but haven't had time to test. Please be aware: it's possible the current snapshot will crash when you try to open a native database -- and gretl tests to see if you have write access to it.] Allin. -- Allin Cottrell Department of Economics Wake Forest University, NC
