Shiny Server Pro and Microsoft R

Shiny Server Pro supports many distributions of R, and can even run applications on a single server with different versions or distributions of R. Your organization may be using a distribution of R shipped by Microsoft such as MRO or MRS. Shiny Server Pro can run applications on-top of these distributions seamlessly.
