A frequent question that we get here at Microsoft about MRO (Microsoft R Open) is: can be used with RStudio? The short answer is absolutely yes! In fact, more than just being compatible, MRO is the perfect complement for the RStudio environment.

If RStudio is not already pointing to MRO (like it is in the screen capture) browse to it, and click “OK”.
One feature of MRO that dovetails nicely with RStudio is that way that MRO is tied to a fixed repository. Every day, at precisely midnight UTC, the infrastructure that supports the MRO distribution takes a snapshot of CRAN and stores it on Microsoft’s MRAN site. (You can browse through the snapshots back to September 17, 2014 from the CRAN Time Machine.) Each MRO release is pre-configured to point to a particular CRAN snapshot. MRO 3.2.3, for example, points to CRAN as it was on January 1, 2016. Everyone who downloads MRO is guaranteed to start from a common baseline that reflects CRAN and all of its packages …read more
