KeyError: "Unknown key: 'ar_order'."

Thanks for your great work. I got the following error, running
results = pyhrv.hrv(nni=nni_base) on Python3.7

Would you please help me.

Thanks for submitting the issue! I already fixed this malfunction and it will be available int he next pyHRV available which I am planning to release over the next couple of days.

Hello Pedro, thank you for your work! When do you plan to release this new fix?

[PGomes92]

Hi Thiago, thanks for the positive feedback, I am glad to hear that pyHRV has left a good impression!

Unfortunately, I am a bit behind my planned scheduled update for pyHRV but I am trying to get the new update with a lot of new features and bug fixes (incl. this one) over the next week.

Hi Pedro!

first of all thank you for your great work. Unfortunately I have been getting the same error as in this issue. Can you please tell me when you will be able to fix this?

Thanks again
Philipp

For those who interested in a quick and dirty fix: replace the line 906 of frequency_domain.py with something like:
ax.set_title("PSD - Autoregressive (DIRTY FIX)")

Closed with update v.0.4.0
