R & RStudio hardware Utilization
The actual question posed was whether R behaves differently than RStudio at parallel computation, which is like asking whether apple pies grow better than apple trees. The answer is that RStudio doesn't do any computation... it is a programming environment that hands off all computation to a separately-installed copy of the R software. Read the messages in the console right after you start RStudio instead of ignoring them. -- Sent from my phone. Please excuse my brevity.

I am going to attend MSc Data Science in September, so I consider
upgrading my system to be more efficient with my projects.I used RStudio for my Macroeconomics Undergraduate Thesis and I had a couple of loops which needed almost 30 minutes to occur.
My system specifications are the following: - CPU: i7 4970k @ 4.0 GHz - RAM: 8GB DDR3 - Hard Drive: SSD M.2 950 PRO Since I have only used RStudio, is there any dramatic difference
between R and RStudio in terms of system resources used?
Does R utilizes all Cores? If it does, is it better to go for more
cores or faster CPU?I know that RAM has a great impact. However, I don't really know how much do I really need for individual projects. Invest to 32GB or just go for fast 16GB?At the moment, my SSD seems fine in terms of speed.
Sorry for the trouble but there is not any clear answer in the
internet. Nonsense!! Searching on "Does R use multiple cores on a multicore CPU" immediately brought this up: https://stackoverflow.com/questions/4775098/r-package-that-automatically-uses-several-cores This appears to answer all your questions! Note in particular the pointers to CRAN's "High Performance Computing" task view, which should provide up to date answers and packages. Cheers, Bert
Thank you in advance,William
