Depending on if you need the data in the referenced environments later, you
could fit the model normally and use the refhook argument in
saveRDS/readRDS to replace references to environments in the model with a
dummy value.
normal_lm <- function(){
junk <- runif(1e+08)
lm(Sepal.Length ~ Sepa

Reviving an old thread. I haven't noticed this be a problem for a while
when saving RDS's which is great. However, I noticed the problem again when
saving `qs` files (https://github.com/traversc/qs) which is an RDS
replacement with a fast serialization / compression system.
I'd like to get an idea
Thanks so much for all this.
The first solution is what I'm going with as I want the terms object to
come along so that predict still works.

Another solution is to only save the parts of the model object that
interest you. As long as they don't include the formula (which is
what drags along the environment it was created in), you will
save space. E.g.,
tfun2 <- function(subset) {
junk <- 1:1e6
list(subset=subset, lm(Sepal.Lengt

One way around this problem is to make a new environment whose
parent environment is .GlobalEnv and which contains only what the
the call to lm() requires and to compute lm() in that environment. E.g.,
tfun1 <- function (subset)
{
junk <- 1:1e+06
env <- new.env(parent = globalenv())
In the below, I generate a model from an environment that isn't
.GlobalEnv with a large object that is unrelated to the model
generation. It seems to save the irrelevant object unnecessarily. In
my actual use case, I am running and saving many models in a loop that
each use a single large data.fram
