Yes, that is correct. My question was about using the R programming language and its libraries rather than RStudio.

If you create a program that uses any of the GPL licensed R libraries, that program must also be GPL licensed [1].

Additionally, the GPL license prohibits using GPL licensed software in proprietary systems [2].
