A package of custom activities that provides seamless **integration of UiPath with R. Use R Scope** and **Run R Script activities** to invoke your prediction and machine-learning models direct from UiPath.

Considered as one of the top software tools for Analytics/Data Science/ML, R is a free software environment for statistical computing. In 2018, R was ranked in the top 10 programming language by popularity (IEEE Spectrum), which shows the importance of having a package in UiPath available for integrating RPA with scripts created in this language.

In addition, we are all aware that Big Data has hit the mainstream by now and many companies have been working with data scientists to analyze their data so that they can create models to forecast budget, predict sales, categorize different type of information and so forth, be it in Finance, Human Resources, or any other area. For this work, data extraction plays an important role and we can think of sources like SAP, Salesforce, or any other existing web system being part of it. So, when automation hits these processes, the combination of RPA with existing scripts created by these data scientists works like a charm.

  

The purpose of this package of custom activities is to provide seamless integration of UiPath and R to make the best experience for RPA developers working on such business scenarios.

The main two activities of this package are **R Scope** and **Run R Script**.

The package was created using the **RDotNet library** distributed through Nuget (https://www.nuget.org/packages?q=R.NET.Community).

\*Not yet compatible with R versions &gt; 3.4.3 \*

  

Future improvements:

*   Compatibility with the recent versions of R.
*   More activities to translate the SymbolicExpression object which outputs from the Run Script activity.
*   More activities to interact with R (install packages, etc.).
*   A better file selection for the Run R Script activity, to display the file explorer for easier file browsing and also enable relative paths to be used.
