Determining memory usage of objects?

Question

I'd like to work out how much RAM is being used by each of my objects inside my current workspace. Is there an easy way to do this?

Answer 1

Hi there,

You can easily check the memory of your R objects by downloading and loading the "pryr" package.

Check the following output. Feel free to run the code yourself:

> install.packages("pryr")

> library(pryr)

> set.seed(666) # set a seed for replicability

> x1 <- rnorm(10) # Small object to test

> object_size(x1)

176 B

> x2 <- rnorm(100000000) # large object to test size

> object_size(x2)

800 MB
