What are R visuals in Power BI?
What are R Visuals? The Power BI service supports viewing and interacting with visuals created with R scripts. Visuals created with R scripts, commonly called R visuals, can present advanced data shaping and analytics such as forecasting, using the rich analytics and visualization power of R.
Can R be used for data visualization?
R is a language that is designed for statistical computing, graphical data analysis, and scientific research. It is usually preferred for data visualization as it offers flexibility and minimum required coding through its packages.
Is R better for data visualization?
Prefer R for data analysis projects, due to its advanced data visualization capabilities. Python is most suitable for machine learning and is also an excellent tool for data science pipelines.
What is an R visual?
Visuals created with R scripts, commonly called R visuals, can present advanced data shaping and analytics such as forecasting, using the rich analytics and visualization power of R. Note.
What are R features?
Features of R R provides a suite of operators for calculations on arrays, lists, vectors and matrices. R provides a large, coherent and integrated collection of tools for data analysis.

Power BI Introduction: Working with R Scripts in Power BI Desktop ...
The group_by function prepares the data for use by another function, which in this case is summarize (also written as summarise).In this example, the summarize function is used in conjunction with the mean function to find the mean for each of the four measures, grouped according to the values in the Species column.. Returning now to the R statement above, notice that the aggregated data is ...
Why is the color aesthetic removed?
The color aesthetic was removed because facets are being applied. The resulting plot diplayed on the Power BI canvas contains subplots and as with the previous plot, it is dynamic. That means it responds to Power BI filters and selections.
How many rows are in a deconstructed table?
The deconstructed table now contains 49 rows based on the quantity specified in the original table. This technique can also be used to create data if there are insufficient rows to represent all the potential classes that can be represented in the data. Another reason to use this approach is that Power BI scripts want to remove duplicate data. Using this approach, detail can be constructed as necessary to meet analytic requirements.
How many tables are created after a script is executed?
After the script is executed, two tables have been created. The original source table and the de-constructed table.
What is the goal of auto sales data?
Below is sample auto sales data provided in aggregate in an Excel spreadsheet. The goal is to deconstruct the data to get to a pseudo-transaction level. Rows correspond to the summarized quantity. This type of transformation can be easily performed using R.
Is R a visualization?
There are many more complex visualizations available in R. If you are looking for a visualization that is not readily available, consider some of the R graphics packages. The learning curve is not too steep and it is well worth the effort to get that little something extra into your visualizations.
Is R a powerful tool?
R is an extremely powerful tool. However, this power does come with some complexity. There are multiple IDEs, thousands of packages and a myriad of approaches and methods for accomplishing the same task.
Can R transform data?
R has an extensive capability to manipulate and transform data. There may be instances where it is necessary to transform data after it has been imported into Power BI in a way that is somewhat challenging to implement in Power BI. One example is data is at an aggregate level but for the purposes of data analysis it needs to be deconstructed. Granted, this is a very specific use case but it goes to demonstrate the capabilities of R and Power BI. Here is an example where data Is only available at the aggregate level but does not provide enough information for prediction. The data will be de-constructed to provide the necessary observations.
Integrating R with Power BI
Microsoft Power BI Desktop version nicely integrates with R. R is an open source software for statistical computing and graphics. R has become popular among the data scientists because of its powerful data analytics and visualization capabilities. Power BI is Microsoft’s flagship BI tool for creating dashboards and interactive reports.
Application 1: Using R to import data sets into Power BI
Power BI can import data from a variety of sources. For a complete list, please see here.
Application 2: Using R to query existing data in Power BI
This application is useful for manipulating an already imported dataset. That is, data have been imported into Power BI Desktop, and now you want to do some cleaning or perform transformations. Essentially, you could do all of those while importing the data (Application 1).
Application 3: Creating visuals with R script
One of the best applications of R with Power BI is that you can harness the power of R to create high quality graphs and display them within your report/dashboard in Power BI. All the filters/slicers will work as usual and the graphs will the dynamically updated when you slice your data.
Using The Help Documentation In RStudio
If you’re not sure about a function and want to learn about the arguments that it takes, you can use the question mark operator (?). As an example, let’s see look at the Help documentation of the plot function by typing ?plot.
Setting Up Power BI With R And RStudio
After the brief introduction of RStudio, let’s proceed with how to configure R in Power BI. First, open Power BI on your desktop. Go to File and select Options and settings. Then, select Options.
Conclusion
R and RStudio are great complementary tools to use in Power BI. They are especially useful when dealing with statistical data and analysis. Configuring them to work with Power BI is quick and easy.
