RStudio is a platform, and a company, focused exclusively on R programming – it dates back to 2009. That's several years before the launch of Project Jupyter, though IPython has been in development since 2001. I'd love to see RStudio branch out and provide feature-for-feature Python functionality (at least), but I don't think that's likely to happen.
