 If you save something to an environment that isnt the Global
Environment then R won't save it when you quit and save. Suggest you
save credentials in a list. Maybe something like this:


then you just get user and password from the environment when needed:


saving the R workspace in the usual way (answering 'y' to Save
Workspace Image) won't save this data.

 I have a vague memory of Splus possibly having a temporary
environment which would do what you want, but that doesn't seem to be
present in R...
