Description

This function handles the core melting operation for multiple entries in an indexed data.table. It is used internally by fhir_melt() to separate multiple entries in a given set of columns into individual rows.

Usage

fhir_melt_internal(indexed_dt, columns, brackets, sep, id_name, all_columns)

Arguments

indexed_dt	A data.table with indexed multiple entries.
columns	A character vector specifying the names of all columns that should be melted simultaneously. It is advisable to only melt columns that belong to the same repeating attribute.
brackets	A character vector of length two, defining the brackets used for the indices.
sep	A character vector of length one, the separator that was used when pasting together multiple entries.
id_name	A character vector of length one, the name of the column that will hold the identification of the origin of the new rows.
all_columns	A boolean indicating whether all columns should be returned (default is FALSE).

Value

A data.table where each entry from the variables in columns appears in a separate row.
