[SOLVED] Is it possible to move a variable from the global environment into a separate environment?

Is it possible to move a variable from the global environment into a separate environment?

Is it possible to move variables that reside in the global environment into a separate environment to declutter the global namespace? I understand how to create variables in a separate environment (with(env, ...)) but is there an efficient way to move them after creation in the global environment. I suppose it would be possible to copy them into a separate environment and then remove them from the global environment, but wanted to know if there was a more efficient manner.

Solution

Maybe:

library(purrr)

a <- 111
b <- 'hello'

my_envir <- new.env()

names(.GlobalEnv) %>% 
    walk(~ assign(.x, get(.x), envir = my_envir))

eapply(my_envir, function(x) x)
#> $my_envir
#> <environment: 0x7fed59e56dc8>
#> 
#> $a
#> [1] 111
#> 
#> $b
#> [1] "hello"

library(purrr)
a <- 111
b <- 'hello'
my_envir <- new.env()

eapply(.GlobalEnv, function(x) x) %>% 
    discard(is.environment) %>% 
    {walk2(., names(.), ~{
               assign(.y, .x, envir = my_envir)
               exec('rm', .y, envir = .GlobalEnv)}
)}


eapply(my_envir, function(x) x)
#> $a
#> [1] 111
#> 
#> $b
#> [1] "hello"
