Unicorn Dream

Minor Improvements

• The knit_print()-method for textstat objects does not accept the three dots argument any more. As an installation of pandoc is necessary to include resulting htmlwidget in an html document, the method will check now whether pandoc is available. If not, a formatted data.table is returned.
• The knit_print()-method for kwic objects does not have the pagelength argument any more as it has been unused. The pagelength is controlled by the option polmineR.pagelength. Internally, the method will call the method for the textstat superclass of the kwic class, which is newly robust against a missing installation of pandoc.
• Any Unicode characters that could be detected have been removed from the documentation to avoid warnings on the CRAN Solaris test machine (#156).

Bug Fixes

• The chisquare() method needs to increase the number of digits temporarily, but failed to revert to the original value as expected. One implication was, that rounding the values in data.table objects would fail, and rounding in general yielded very strange results (#155). Fixed.
