New to R, running R 4.0.3 on Win7. Not sure what went wrong. Several errors, help is much appretiated:

"Bundesland" | "Landkreis" is not correct syntax. Same holds true for Bundesland | Landkreis | Gender | Age. Maybe our example code is a bit confusing.

You can call either covid19germany::get_RKI_spatial("Bundesland") or covid19germany::get_RKI_spatial("Landkreis"). And either covid19germany::group_RKI_timeseries(data, Bundesland) or covid19germany::group_RKI_timeseries(rki, Age), ...

I used the readme examples.

Thank You, now I understand, sorry my fault. Still got this error:

covid19germany::group_RKItimeseries(data, Bundesland) Fehler in UseMethod("select") : nicht anwendbare Methode für 'select_' auf Objekt der Klasse "function" angewendet

I made the example code more clear now. Please try this:

rki <- covid19germany::get_RKI_timeseries()
covid19germany::group_RKI_timeseries(rki, Bundesland)

Thanks You, it is working! I see my problem now. Willt try to work with it now without bothering you.
