You see, if you are new to R, the best option to learn is to take advantage of what RStudio has to offer. In fact, there are many reasons why you should use RStudio instead of R if possible.
One of the major drawbacks of the regular R version is that it does not have a full featured text editor. If you want to use syntax highlighting, etc., unfortunately that's not possible. Having a good text editor makes a big difference when trying to learn a new programming language.
Sometimes we don't know where the text file of all our great code has gone. That's because R doesn't group windows, but RStudio does. All related windows are tied together, which makes it easier to find them when compared to using the regular R version.
RStudio has the option to autocomplete text for users. Just press the key Tab
and the tool will try to fix your mistake. But note that it doesn't always make the right decision.
The regular R version has an old user interface, but that's good for advanced users who already know what they're doing. Not to mention, the minimalist interface ensures flexible performance, so there's no need to invest in a powerful computer.
Despite all that, many people still prefer RStudio because it displays a full list of objects in the panel located at the top right. It has a useful feature and perhaps even advanced users want to use.
