mem_used: How much memory is currently used by R?

Description

mem_used() wraps around gc() and returns the exact number of bytes currently used by R. Note that changes will not match up exactly to obj_size() as session specific state (e.g. .Last.value) adds minor variations.

Usage

mem_used()

Examples

# NOT RUN {
prev_m <- 0; m <- mem_used(); m - prev_m

x <- 1:1e6
prev_m <- m; m <- mem_used(); m - prev_m
obj_size(x)

rm(x)
prev_m <- m; m <- mem_used(); m - prev_m

prev_m <- m; m <- mem_used(); m - prev_m
# }
