Changes in snowfall 1.84 =========================== o Bugfix sfExport: if exporting a NULL value, no error is raised. Changes in snowfall 1.83 =========================== o sfIsRunning: new function giving a logical is sfInit() was called or not. Needed, as all other snowfall functions implicitely call sfInit() if it was not called. Changes in snowfall 1.82 =========================== o Internal refactorings. Changes in snowfall 1.81 =========================== o Change in sfInit() MPI startup so sfCluster can run with snow > 0.3 now. o sfExport now also works in sequential mode (writing to global environment). This prevented sequential execution in some cases. Changes in snowfall 1.80 =========================== o snowfall passes packages checks of R 2.10.1 without warning or error. Internal state is now only saved in the namespace itself (thanks to Uwe Ligges for the tipp). o sfExport can now also export objects in a specific namespace (argument 'namespace') o sfExport: behavior in error case manageable (stopOnError) o sfExport: smaller bugfixes. o sfRemoveAll can now also remove hidden names (argument 'hidden') o sfRemoveAll is more robust now (some minor bugfixes, more checks) o sfRemoveAll bugfix for multiple removals (thanks to Greggory Jefferis) o Bugfix on exception list on sfExportAll o Refactorings in sfTest() o snowfall now has a NEWS doc ;) o No warning on Mac OS because of default Mac-R command line arg 'gui' (thanks to Michael Siegel).
