[Gretl-announce] grep 2022b released

As usual, see http://gretl.sourceforge.net/index.html 2022-08-09 version 2022b - new command/keyword "continue" for use in loops - new option --decr for use with index loops - new function commute(): pre/post multiplication by the commutation operator (replaces analogous function in the extra addon) - new function sphericorr(): spherical coordinates representation for correlation matrices - "garch" command: add the model order scalars (p and q) to the $model bundle - "leverage" command: add $result accessor to obtain leverage, influence and studentized residuals as matrix - "pergm" and "fractint" commands: use FFT for computing the spectrum - "printf" command: add "\r" as a recognized escape sequence - "smpl" command: add --dates option to resolve potential ambiguity of obs limits in case of annual and daily data - "markers" command: add --from-series option - "store" command: support saving a gretl session file (only in the GUI program), given the ".gretl" suffix - "vecm" command: redefine the "order" member of the $system accessor to give the lag order in levels, consistent with the vecm documentation - assert() function: add a "fatal" switch to abort program execution when an assertion fails - deseas() function: add the option of saving the X-13ARIMA specification created by gretl; add option to specify the ARIMA model; document the verbose option - qrdecomp() function: support column pivoting, via new optional third argument - weekday() and isoweek() functions: generalize to accept dates in ISO 8601 "basic" format - rank() and ginv() function: add optional tolerance argument - Support direct assignment from string-values series to array of strings - script editor: enhancements for Find/Replace dialog - GUI viewer windows: support Ctrl-plus and Ctrl-minus to increase/reduce font size - R support: enable exchange of matrices in binary format - Fix bug: failure of dbnomics download on Windows when a very large number of series is specified - Fix bug: crash on use of the --full option with "restrict" when applied to the alpha terms in a vecm - Fix bug: breakage in GUI item "X-13ARIMA analysis" - Fix bug: crash on trying to stringify() an empty series - Fix bug: det() should not flag an error when returning NA - Fix bug: make "set loop_maxiter 0" behave as advertised - Fix bug: misbehavior when subsampling within a function a panel dataset that was subsampled prior to calling the function in question - Fix bug: the 'end' keyword for indexing into matrices could fail under certain conditions - Fix bug: obsnum() producing unwanted results in case of 5- or 6-day daily data - Fix obscure issue: ensure that libR gets a correct value for R_HOME when the user has specified the location of libR.so as a symlink (probably specific to Linux, and confined to the context of gretl's "foreign language=R") - Fix GUI bug: the option of showing lagged series in a selection dialog not always available when it should be - Fix GUI bug: incorrect behavior of function-call dialog when defining a new list - distribution: remove unused file, addons.txt Plus a couple of new features which are not yet "official" but are available for testing - Dedicated script editor (not on macOS yet): see http://gretl.sourceforge.net/papers/gretl_edit.pdf - New state space functionality; see http://gretl.sourceforge.net/papers/ksecrets.pdf -- Allin Cottrell Department of Economics Wake Forest University
