I have four years in the R trenches, and code in R on the Ubuntu
command line and the Windows R GUI.
Here is an RStudio comparative overview:
In the absence of Rstudio, to construct and debug a script I need:
1) A programmer's editor (such as VIM (bad) or Bluefish (better)), in
which I enter the script
2) The R GUI / command/console window to run the script
To test / debug the script: use the source() function to load and execute.
To pause the script: insert browser(); statements at desired stopping points
(thus adding needles complexity to the code)
To view variable contents: use the message() and sprintf() functions to
print text
Viewing R help files using the ?() command opens another popup window or
windows with the help files.
These must be manually closed when not needed.
When using RStudio, I need:
*Only* the RStudio app running - its GUI includes:
- A very good color-coded programmer's editor,
- The R console, and (when activated), an excellent debug
information window.,
- The Debug information window, which displays execution information
(e.g., variable values),
once the debugger is activated (see below)
- The R documentation window, to display help files.
To step through / debug the R script: Use RStudio's integrated
debugger, which takes approximately 5 minutes to learn.
for more info:
https://support.rstudio.com/hc/en-us/articles/200713843-Debugging-with-RStudio?version=0.98.1091&mode=desktop
OR within RStudio, select Debug/Debugging Help
The quality and usability of RStudio has markedly improved since the
early versions: Most beginner-level R programmers can become comfortable
using RStudio in 45 minutes. They will recoup their time investment
within the first three hours of R development.
Hope this helps,

That is what websites are for. Go to rstudio.com and make your own judgment
. I have found that they provide much useful functionality above and beyond
R's bare bones GUI.

Could someone kindly enlighten me whether there are currently advantages
to use R Studio vs. the normal R GUI? On the Mac I can't seem to find
anything compelling, on Windows (which I don't use myself) I noticed last
year that there seems to be no syntax highlighting available for the R GUI
but R Studio had it.
Surely there must be some value proposition in that project, what am I
missing?
Thanks,
Boris
