This is a fair point; structuring functions into packages is probably ultimately the gold standard for code organization in R. However, lexical scoping in R is really not much different than in other languages, such as Python, in which use of main functions and defining other named functions outside of main are encouraged. For example, in Scheme, from which R derives its scoping rules, the community generally organizes code with almost e...

In R scripts (as opposed to packages), even in reproducible scripts, it seems fairly conventional to use the global workspace as a sort of main function, and thus R scripts often populate the global environment with many variables, which may be mutated. Although this makes sense given R has historically been used interactively and this practice is common for scripting languages, this appears to
