General A test-suite was added to the package. Updated reference in CITATION to the publication in the Journal of Open Source Software. New functions is_cross_classified() to check whether two factors are partially crossed. Changes to functions ref_lvl() now also accepts value labels as value for the lvl-argument. Additionally, ref_lvl() now also works for factor with non-numeric factor levels and simply returns relevel(x, ref = lvl) in such cases. Bug fixes Fixed encoding issues in rec() with direct labelling for certain locales. Fixed issue in count_na(), which did not print labels of tagged NA values since the last revision of frq(). Fixed issue in merge_imputation() for cases where original data frame had less columns than imputed data frames. Fixed issue in find_var() for fuzzy-matching in all elements (i.e. when fuzzy = TRUE and search = "all").
