You might like to try pryr::object_size() : ``` r library(pryr) env1 <- new.env() object_size(env1) #> 328 B env2 <- new.env(hash = TRUE, size = 75000000L) object_size(env2) #> 600 MB env3 <- list2env(list(a = runif(2.5e+07), L = LETTERS)) object_size(env3) #> 200 MB ```
It handles the issue that Gabe mentions: ``` r a <- list2env(list(a = runif(1e+06))) object_size(a) #> 8 MB b <- new.env() b$a <- a b$b <- runif(1e+06) object_size(b) #> 16 MB object_size(a, b) #> 16 MB ``` You just have to remember that object_size(a) + object_size(b) <= object_size(a, b).
