Weekly frequency

[kamecon]

Hi!

I'm using weekly data and I define frequency = 52 in geom_sa, but I get the following error:

Warning message:
Computation failed in stat_sa():
Couldn't pick automatically the frequency: you must specify manually the argument 'frequency'

Thanks!

Hi,
ggdemetra is based on RJDemetra which is based on the JDemetra+ software (https://github.com/jdemetra/jdemetra-app). For the moment, you cannot perform seasonal adjustment on weekly data with the methods implemented by JDemetra+ (X-13 and TRAMO-SEATS): you can only use monthly, bimonthly (with TRAMO-SEATS), quarterly and half-yearly data. However, by the end of 2019 the methods will be improved to be compatible with all the infra-annual frequency (weekly, daily, etc.).
To conclude, for the moment you cannot use weekly data but you will be able in the future. I will also improve the error message in ggdemetra.

Thanks @AQLT !

I hope the extensions will be available in the near future!
