How can I determine how much memory a given piece of my code is
allocating (directly or indirectly)? -- essentially, the space
analogue of system.time, something like this:
system.space( x <- rnorm(10000) )
10000 Vcells
system.space( for (i in 1:1000) x <- rnorm(10000) )
10000000 Vcells
I'm not looking for anything as fine-grained as Rprofmem or tracemem,
just the overall allocations. I'm also not looking for the amount of
*live* memory (that is, net of garbage collection) as reported by
memory.profile or gc.
Thanks,
