as_data_proc_elem: Validate and coerce as a Data Processing Elements object

In Rmonize: Tools for Data Harmonization

Validate and coerce as a Data Processing Elements object

Description

Checks if an object is a valid Data Processing Elements and returns it with the appropriate Rmonize::class attribute. This function mainly helps validate inputs within other functions of the package but could be used separately to ensure that an object has an appropriate structure.

Usage

as_data_proc_elem(object)

Arguments

object

A potential Data Processing Elements object to be coerced.

Details

The Data Processing Elements specifies the input elements and processing algorithms to generate harmonized variables in the DataSchema formats. It is also contains metadata used to generate documentation of the processing. A Data Processing Elements object is a data frame with specific columns used in data processing: dataschema_variable, input_dataset, input_variables, Mlstr_harmo::rule_category and Mlstr_harmo::algorithm. To initiate processing, the first entry must be the creation of a harmonized primary identifier variable (e.g., participant unique ID).

Value

A data frame with Rmonize::class 'data_proc_elem'.

Examples

{

# Use Rmonize_examples to run examples.
library(dplyr)

data_proc_elem <- as_data_proc_elem(Rmonize_examples$`Data_Processing_Elements_no_errors`)

head(data_proc_elem)

}
