harmonize_var_names: Harmonize the variable names of surveys
In retroharmonize: Ex Post Survey Data Harmonization

Description Usage Arguments Details Value See Also Examples

The function harmonizes the variable names of surveys (of class survey) that are imported from an external file as a wave.

harmonize_var_names(
  waves,
  metadata,
  old = "var_name_orig",
  new = "var_name_suggested",
  rowids = TRUE
)

`waves`	A list of surveys imported with `read_surveys`.
`metadata`	A metadata table created by `metadata_create` and binded together for all surveys in `waves`.
`old`	The column name in `metadata` that contains the old, not harmonized variable names.
`new`	The column name in `metadata` that contains the new, harmonized variable names.
`rowids`	Rename var labels of original vars `rowid` to simply `uniqid`?

If the metadata that contains subsetting information is subsetted, then it will subset the surveys in waves.

The list of surveys with harmonized variable names.
