I am currently working through Advanced R by H. Wickham and came
across the `lobstr::obj_size` function which appears to calculate the
size of an object by taking into account whether the same object has
been referenced multiple times, e.g.
x <- runif(1e6)
y <- list(x, x, x)
# 8,000,128 B
# 24000224 bytes
Reading through `?object.size` in the "Details" it reads: [...] but
does not detect if elements of a list are shared [...].
My questions are:
(1) is the result of `obj_size()` the "correct" one when it comes to
actual size used in memory?
(2) And if yes, why wouldn't `object.size()` be updated to reflect the
more precise calculation of an object in question similar to
There are probably valid reasons for this and any insight would be
