Harmonise Raw IHS Data

Takes a raw data.frame loaded from a Malawi IHS survey round (e.g. from a `.dta` file) and renames its columns to the standard harmonised variable names defined in the crosswalk.

Usage

ihs_harmonise(data, round = "IHS5", extra = FALSE)

Arguments

data

A data.frame, typically read from a `.dta` file using haven::read_dta.

round

A character string specifying the IHS round (e.g., "IHS5", "IHS4").

extra

Logical. If FALSE (default), drops columns that are not in the harmonisation crosswalk or standard ID columns. If TRUE, keeps all original columns.

Value

A data.frame with columns renamed to standard `harmonised_name`s where applicable.
