What is the difference between Microsoft Open and Rstudio?

Rstudio is either Microsoft Open or Rstudio because of the documentation fidelity.

In conclusion,
Neither Microsoft Open nor Rstudio is recommended.There are many disadvantages such as "low scalability," "unintuitive and difficult to use features such as markdown," and "less documents."

If you want to use it, please think about the future and use the jupyter notebook.
The jupyter notebook originated from Ipython, which was originally developed for python, but is now available in all languages.There are a lot of environmental building procedures, but I definitely recommend it.
