[R] Saving environment object

[Henrik Bengtsson]

Hi,

can you please give a reproducible example and what's your sessionInfo()?

Many years ago when I started to develop the Object class in R.oo,
which is using environments, I also had problems saving environments
directly.  I my case I think it was when I added a class attribute to
an environment, but I don't remember the details [theys are somewhere
in the R-devel archives].  I never understood why it didn't work.
What solved my problem was to put the environment as a element of
something before save, e.g. in a list or as an attribute.  So try
this:

env <- new.env();
...
x <- list(env=env);
save("x", file="x.RData");

It might help
