## 7 Missing Functionality ¶

Tablicious is based on Matlab’s table and date/time APIs and supports some of their major functionality. But not all of it is implemented yet. The missing parts are currently:

- File I/O like `readtable()` and `writetable()`
- `summary()` `categorical`
- Assignment to table variables using `.`-indexing
- `timetable`
- POSIX time zone support for years outside the IANA time zone database coverage
- Week-of-year (ISO calendar) calculations
- Various `'ConvertFrom'` forms for `datetime` and `duration` constructors
- Support for LDML formatting for `datetime`
- Various functions:
  - `between`
  - `caldiff`
  - `dateshift`
  - `week`
- `isdst`, `isweekend`
- `calendarDuration.split`
- `duration.Format` support
- Moving window methods in `fillmissing`
- `UTCOffset` and `DSTOffset` fields in the output of `timezones()`
- Plotting support

It is the author’s hope that many these will be implemented some day.

These areas of missing functionality are tracked on the Tablicious issue tracker at https://github.com/apjanke/octave-tablicious/issues and https://github.com/users/apjanke/projects/3.
