Dear R user,

I am using Sweave to write my reports with R code. Unlucly my code take a
lot of time to run, and I don't want to run it multiple time, if possible,
as I am still developping the tools.

It seems that a sweave run does not save the enviroment at the end of the
process, is there a way to avoid to lunch multiple time the same commands?
maybe it could be possible to store chunck of code results, and only call
them in the next runs.

thank you
