prep_fix_meta_id_dups: Fix metadata duplicates

In dataquieR: Data Quality in Epidemiological Research

Fix metadata duplicates

Description

if VAR_NAMES have duplicates, maybe, it's because of ID-vars assigned to different study segments multiple times (they should be in one "intro"- segment, only), which is not the intended use of STUDY_SEGMENT. Naturally, they will be part of more than one data-frame, so this would also qualify for a dump duplicate, only, which can safely be removed. Only ID-vars are by default assumed to have such duplicates in item level metadata allowed.

Usage

prep_fix_meta_id_dups(
  meta_data_segment = "segment_level",
  meta_data_dataframe = "dataframe_level",
  item_level = "item_level",
  meta_data = item_level,
  meta_data_v2,
  segment_level,
  dataframe_level
)

Arguments

meta_data_segment	data.frame – optional: Segment level metadata
meta_data_dataframe	data.frame the data frame that contains the metadata for the data frame level
item_level	data.frame the data frame that contains metadata attributes of study data
meta_data	data.frame old name for item_level
meta_data_v2	character path to workbook like metadata file, see prep_load_workbook_like_file for details. ALL LOADED DATAFRAMES WILL BE PURGED, using prep_purge_data_frame_cache, if you specify meta_data_v2.
segment_level	data.frame alias for meta_data_segment
dataframe_level	data.frame alias for meta_data_dataframe

Value

meta_data

Examples

## Not run: 
il <- prep_get_data_frame("item_level")
il <- rbind(il, il)
il$STUDY_SEGMENT[2] <- "X"
il2 <- prep_fix_meta_id_dups(meta_data_v2 = "meta_data_v2", item_level = il)
il2$STUDY_SEGMENT
il$STUDY_SEGMENT[3] <- "X"
il3 <- prep_fix_meta_id_dups(meta_data_v2 = "meta_data_v2", item_level = il)
il3$STUDY_SEGMENT

## End(Not run)
