I am currently working through Advanced R and came across the
lobstr::obj_size function which correctly calculates 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) obj_size(y) # 8,000,128 B object.size(y) # 24000224 bytes
In the Environment pane in R Studio the size of
y is listed as 22.9 Mb, similar to
object.size(y). Is there a reason for this? Wouldn't it be better to show the size one gets with
obj_size(y) since this is more accurate?
