eatGADS 1.1.0

new features

• equalGADS() now allows pre-sorting the data by an identifier variable
• updateMeta(), applyChangeMeta(), changeVarNames(), cloneVariable(), createVariable(), composeVar(), and dummies2char() now have optional checks of new variables names via the checkVarNames argument
• reuseMeta() now can be use on multiple variables at once
• inspectMetaDifferences() now can be applied to data bases as well
• recodeNA2missing() for recoding NAs to a specific missing code
• recode2NA() now allows the recoding of multiple values at once and returns a warning, if the recoded values have existing value labels in the recoded variables
• updateMeta() is now compatible with extractData() and extractData2()
• S3 method of extractData2() now available for trend_GADSdat objects
• recodeGADS() and applyChangeMeta() allow recoding values without recoding value labels (via existingMeta = "ignore")

bug fixes

• import_spss() now removes duplicate meta data rows, which caused an error in, e.g., recodeGADS()
• export_tibble() and write_spss() now throw an error if a conversion of four or more discrete missing tags into a missing range has undesired side effects
• bug fix in checkMissingsByValues(), now correctly reports missing tags outside of the specified value range
• bug fix in cloneVariable(), now new variables names which are also SQLite keywords no longer throw a error (fixed conflicts caused by checkVarName())
