Is there a way to save EVERYTHING in R?

Hi all,

Could you please shed some lights on me about this?

I am trying to see if there is a way to save EVERYTHING in R to a file,
something like "save.image"...

But "save.image" doesn't save environment variables such as those
properties that are obtained using "Sys.getenv()" function...

So is there a way to save EVERYTHING?

Thanks a lot!

Well, the answer is yes, but not as you expect: If you have a virtual 
machine running only accessing a local filesystem, you can create a 
snapshot.

So, for other practical purposes and in the sense but not wording of you 
question:
No, environment variables are part of the OS (or the shell).
If you want to save EVERYTHING this way, you'd need an image of both, 
the RAM of you machine as well as the current state of all filesystems etc.

Best,

No.

Write a script that reconstructs the working environment. Some differences may
remain due to incompleteness of your script. The rest may be due to differences
in the hardware or software environment. Such differences can only be minimized
by choosing stable numerical algorithms or avoiding installation-specific
features, and serve as indicators of how reproducible your work is.
