Shiny | Dispersion crashes, all the time

[ChristophLeonhardt]

Dispersion crashes all the time, both with default options and when changing things around. Tested with polmineR::polmineR(), GermaParlMini and the query "Herr". The error is always:

Error in .cl_str2id(corpus = corpus, p_attribute = p_attribute, str = str, : Expecting a single string value: [type=NULL; extent=0]. |++++++++++++++++++++++++++++++++++++++++++++++++++| 100% elapsed = 00s Warning: Error in check_cpos: all corpus positions (cpos) need to be <= attribute size, not TRUE

This substantial malfunction of dispersion in the shiny app is now solved, with polmineR v0.7.11.9027 (on the dev branch, devtools::install_github("PolMine/polmineR", ref = "dev"). Having worked on this part of the shiny app anyway, more functionality of the dispersion()-method is exposed than before (usage of cqp syntax, for instance).

I am fairly sure that this part of the shiny app is not yet robust and that we will see more specific issues. But as this general issue is addressed, I will close it.
