¶ About
The 'modeleR' action button serves as a foundational template for creating custom R-based ETL (Extract, Transform, Load) components within a visual pipeline interface. It provides a basic scaffold that allows users to define their own data transformation logic in R, making it highly flexible and ideal for advanced users who wish to extend the ETL platform's capabilities beyond standard pre-built components.
In the sample template, the script simply appends a new column with the word "world!" to each row, demonstrating how to manipulate input data in a minimal example. The code supports installing custom R packages and dynamic column creation, and includes a structure to return either full results or just column metadata, depending on execution mode.
¶ How It Works
The action receives input data from upstream ETL components, processes it using user-defined R code, and outputs a transformed table. Parameters such as 'idTable' (input dataset) and 'idJoin' (whether to append columns to the input) are configurable to adjust the execution flow and output structure.
¶ Use Cases
- Prototyping custom R-based data processing steps
- Integrating advanced statistical functions or visualizations from R libraries
- Performing transformations not covered by standard ETL actions
- Extending the platform with domain-specific logic
This button is best suited for data engineers or data scientists comfortable with R who need to implement precise, bespoke transformations within their pipelines.
