Extending Power BI with Python and R

By: Luca Zavarella

Overview of this book

Python and R allow you to extend Power BI capabilities to simplify ingestion and transformation activities, enhance dashboards, and highlight insights. With this book, you'll be able to make your artifacts far more interesting and rich in insights using analytical languages. You'll start by learning how to configure your Power BI environment to use your Python and R scripts. The book then explores data ingestion and data transformation extensions, and advances to focus on data augmentation and data visualization. You'll understand how to import data from external sources and transform them using complex algorithms. The book helps you implement personal data de-identification methods such as pseudonymization, anonymization, and masking in Power BI. You'll be able to call external APIs to enrich your data much more quickly using Python programming and R programming. Later, you'll learn advanced Python and R techniques to perform in-depth analysis and extract valuable information using statistics and machine learning. You'll also understand the main statistical features of datasets by plotting multiple visual graphs in the process of creating a machine learning model. By the end of this book, you’ll be able to enrich your Power BI data models and visualizations using complex algorithms in Python and R.

Choosing an R engine to install

Once you have decided on the R distribution to install, the first question when installing an R engine is: "Which version should I install? Do I choose the latest one, or do I opt for a previous one?" The usual answer to these kinds of questions is: "It depends!". In our case, the goal is to use the R engine within Power BI, so we need to understand which versions are used by the different products that admit the use of R within them.

The R engines used by Power BI

We saw in Chapter 1, Where and How to Use R and Python Scripts in Power BI, that only two Power BI products are allowed to use scripts in R and Python: Power BI Desktop and the Power BI service (remember that Power BI Embedded is implicitly included when talking about the Power BI service). So, the answer "It depends!" takes on a clearer connotation now: if you need to share your reports with people inside your organization, then you have to install the...
