I find the global options in RStudio incredibly helpful and think that they encourage best practice of script writing, reproducibility and good style.
I have made an installation package for R and RStudio for users in my company. I would like to set some of the Global Options on install such as de-select "Always save history", set, "save workspace to .RData on exit" to never and select "Provide R style diagnostics".
Unfortunately, it is not yet possible to (easily) programmatically modify RStudio's global / project options. This is something we're considering for a future release of RStudio.
