[R] setting options only inside functions

[Jonathan Daily]

I would also love to see this implemented in R, as my current solution
to the issue of doing tons of open/close, dev/dev.off, etc. is to use
snippets in my IDE, and in the end I feel like it is a hack job. A
pythonic "with" function would also solve most of the situations where
I have had to use awkward try or tryCatch calls. I would be willing to
help with this project, even if it is just testing.
