making object.size() more meaningful on environments?
Herve, The problem then would be that for A a refClass whose fields take up N bytes (in the sense that you mean), if we do B <- A A and B would look like the BOTH take up N bytes, for a total of 2N, whereas AFAIK R would only be using ~ N + 2*56 bytes, right? ~G

Hi, Currently object.size() is not very useful on environments as it always returns 56 bytes, no matter how big the environment is: env1 <- new.env() object.size(env1) # 56 bytes env2 <- new.env(hash=TRUE, size=75000000L) object.size(env2) # 56 bytes env3 <- list2env(list(a=runif(25000000), L=LETTERS)) object.size(env3) # 56 bytes This makes it pretty useless on reference class instances and other objects that use environments internally for caching or other purposes. What about changing this and make it return something more meaningful? Cheers, H. -- Herv?
