Rstudio is one of the few IDEs that exist for programming in R because it is a very recent language and still little known, for this the editor Rstudio although it has little development time I think it is an application that is very well built and that works suitably for the creation of large projects using R as a language.
Technically it is very similar to other IDE created for other languages so if you are a programmer you probably do not find it hard to understand. The application in terms of configuration seemed complete and has all the features that one needs to build an efficient workspace in any IDE.
On the one hand it allows the change of appearance to a darker theme, something that we appreciate those of us who have a sight that gets tired easily when programming in environments with a lot of light. It also has a very useful command console for the execution or compilation of the project.
Sincerely, I found it to be a very well-built application that has nothing to send to other IDE, Rstudio provides an environment to program in R that offers everything necessary for the creation and debug of any project. Maybe silly but you call it something negative it could be the default theme that although I like it, it could be a dark one by default since most programmers prefer a dark one.
I would recommend using RStudio not only because you really do not have an option since it is the only IDE alternative for R that is worthwhile, if not because it is really a good IDE that offers everything necessary for the creation of any project in this language, In addition the IDE has several versions, free and enterprise, but you can try it before buying it.
