sjmisc: Data and Variable Transformation Functions

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").
