mde version 0.2.0 Additions na_summary which provides a very quick overview of missingness. It also supports grouped summaries. drop_na_if allows easy dropping of columns where all values are missing. custom_na_recode allows replacing missing values with common values such as mean, min, max, sd. Major changes In percent_missing, the argument grouped was dropped in favour of simply providing a grouping_cols vector. In recode_as_na , subset_df was dropped. It now simply accepts an optional subset_cols argument. The argument tidy was also dropped.One can simply provide an optional pattern_type and pattern. Similar changes were made for recode_na_as as above. The argument x was changed to df in drop_na_at.
