Microsoft R Client is a free, community-supported, data science tool for high performance analytics. R Client is built on top of Microsoft R Open so you can use any open-source R package to build your analytics. Additionally, R Client includes the powerful RevoScaleR technology and its proprietary functions to benefit from parallelization and remote computing.

R Client allows you to work with production data locally using the full set of RevoScaleR functions, but there are some constraints. Data must fit in local memory, and processing is limited to two threads for RevoScaleR functions. To work with larger data sets or offload heavy processing, you can access a remote production instance of Machine Learning Server from the command line or push the compute context to the remote server. Learn more about its compatibility.

While R is a command-line driven program, you can also use your favorite R integrated development environment (IDE) to interact with Microsoft R Client. To do so, you must point that IDE to the R Client R executable. Tor only protects your applications that are properly configured to send their Internet traffic through Tor. To avoid problems with Tor configuration, we strongly recommend you use the Tor Browser. It is pre-configured to protect your privacy and anonymity on the web as long as you're browsing with Tor Browser itself.

Machine Learning Server vs R Client

Machine Learning Server and Microsoft R Client offer virtually identical R packages, but each one targets different scenarios. R Client is intended for data scientists who create solutions that run locally. Machine Learning Server is commercial software that runs on a range of platforms, at much greater scale, with infrastructure for handling major workloads, on client-server topologies that support remote access over authenticated connections.

You can work with R Client standalone. You can also use it with Machine Learning Server, where you learn and develop on R Client, and then migrate your work to Machine Learning Server or execute it remotely on a Machine Learning Server whenever you need the scale, support, and infrastructure of a server configured for operationalization.

• From R Client, shift on bottom of the file '/opt/microsoft/rclient/3.4.3/runtime/R/etc/Renviron'. Source.

  After you configure the IDE, a message appears in the console signaling that the Microsoft R Client packages were loaded.

  Important

  You can connect remotely from your local IDE to an Machine Learning Server instance using functions from the mrsdeploy package. Then, the R code you enter at the remote command line executes on the remote server. This is very convenient when you need to offload heavy processing on server or to test your analytics during their development. Your Machine Learning Server administrator must configure Machine Learning Server for this functionality.

  3. Try Out R Client

  Now that you've installed R Client, you can start building and running some R code. Launch R on the command line or in your IDE and:

  • Run the sample R code as described in this quickstart guide.

  • Or, develop your own solutions using RevoScaleR functions, MicrosoftML functions, and APIs.

  When ready, you can run that R code using R Client or even send those R commands to a remote Machine Learning Server for execution if Machine Learning Server is also installed in your organization.
