cooccurrences with more than one positional attribute

[ChristophLeonhardt]

In earlier versions of polmineR, it was possible to pass more than one p-attribute to cooccurrences() as illustrated in the slides here (the result is shown on the following slide).

In polmineR 0.8.6.9003 this does not work anymore. Using the example from the slide here, passing one p-attribute still works as expected.

mmh_query <- '"Menschen" "mit" "Migrationshintergrund"'
cooccurrences("GERMAPARL", query = mmh_query, p_attribute = "word")

But adding a second p-attribute as shown in the example throws an error.

cooccurrences("GERMAPARL", query = mmh_query, p_attribute = c("word", "pos"))

Error in .region_matrix_context(corpus = corpus, registry = registry, :
Expecting a single string value: [type=character; extent=2].

Good point. This is the example I use for recovering the ability of cooccurrences() to handle two p-attributes:

corpus("GERMAPARLMINI") %>%
  cooccurrences(query = "Arbeit", p_attribute = c("word", "pos"))

Fixed.
