error in get_seats

[adibender]

Forsa released 2 surveys in one day. Appears to cause errors

[bauer-alex]

Unfortunately the error is still remaining using the updated devel branch:

> library(coalishin)
> crawl_data("btw", oldest_date = "2017-11-19")
> calc_coalProbs("btw", nsim = 2)
[1] "Perform new calculations for emnid..."
Fehler: Variable context not set

Diving deeper in...

... the error occurs when calling get_seats() with the following arguments:

> coalitions::get_seats(dirichlet.draws, survey = survey)
>
> dirichlet.draws

Diving even deeper in...

... the error occurs when calling gather() inside get_seats().

sry, cannot reproduce. From the output it appears as if error occurs for "emnid" data.
Just ran the workflow vignette manually with dates going back before the election ... no errors.

Will need a pure coalitions reprex (no coalishin dependency)
