Posit (RStudio)

Posit (formerly RStudio) is the wildly explosive, absolutely dominant open-source apex predator of the "Data Science and Statistical Programming" market. It engineered a terrifyingly powerful IDE for the R (and Python) programming languages. It is the absolute weapon of choice for the modern generation of data scientists who mathematically demand the absolute freedom of open-source libraries to write custom statistical algorithms that commercial, closed-source software mathematically cannot even comprehend yet.
