.. _fwflag_print_freq_csv:
==================
--print_freq_csv
==================
Switch
======

--print_freq_csv FILENAME

Description
===========

Prints raw group frequencies (rather than group-normalized values) to a csv file — otherwise the same as :doc:`fwflag_print_csv`.

Argument and Default Value
==========================

A file path. Default: ``None``.

Details
=======

**Known issue — the filename you pass is ignored.** ``dlatkInterface.py`` calls ``oa.printGroupsAndOutcomesToCSV(fg, args.printcsv, freqs=True)`` — using ``args.printcsv`` (the value of :doc:`fwflag_print_csv`) instead of ``args.printfreqcsv``. Verified: running ``--print_freq_csv ./x.csv`` alone (without also passing ``--print_csv``) results in ``args.printcsv`` being ``None``, which then fails the same way described below rather than writing to ``./x.csv``.

**Known issue — also MySQL-only.** This calls the same ``oa.printGroupsAndOutcomesToCSV()`` as :doc:`fwflag_print_csv`, which checks table existence via a direct ``mysqlmethods`` call rather than the SQLite-aware abstraction. Verified: fails with ``sqlite3.OperationalError: near "show": syntax error`` under a SQLite corpus.

Other Switches
==============

Required Switches:

* :doc:`fwflag_d`, :doc:`fwflag_t`, :doc:`fwflag_c`
* :doc:`fwflag_f`
* :doc:`fwflag_outcome_table`, :doc:`fwflag_outcomes`

Example Commands
================

.. code-block:: bash

	# Broken as of this writing (see Known issues above) — filename is silently swapped and MySQL only works
	dlatkInterface.py -d dla_tutorial -t msgs -c user_id -f 'feat$1gram$msgs$user_id$16to16' \
	--outcome_table blog_outcomes --outcomes age --print_freq_csv ./freqs.csv
