Hi,

I am writing code in Emacs using org-mode and babel. I have a number of code
blocks that are tangled into several files with some files spanning several
code blocks. Each of these files is supposed to run independently of each
other on a clean version of R, however I also want to be able to execute
each code block during the org-mode development. This means

a) I cannot use a new R session in every code block
b) I cannot reuse the same R session for all code-blocks without cleaning it
up
c) Quitting and restarting R is not an option

Thank you very much for your suggestions for cleaning the workspace. It is a
partial solution, but doesn't guarantee a vanilla state (i.e. inadvertently
changed options and the like). I was hoping for a base-package function that
guarantees this functionality, but will probably use the ad-hoc version of
cleaning the workspace and the packages only if no-one knows anything
else....

Thank you very much for your suggestions again.

Best

Holger
