You didn't give any advice. I did :-)-O And it does what the OP asked 
for :-)-O

I do some things in the command line R or even running stuff as Rscript,
but for development (and updates) an IDE such as RStudio is very helpful
even if it is not die reine Lehre :-)-O

For myself, I would not use RStudio as it does what you describe: Lots

which editor or environment to use, as that is a matter of taste.
