Checking memory usage in R

Wow, I cannot believe I didn’t blog this. I just tried to find it on my own blog and I must have forgotten. Anyway, it’s an answer I gave on Stack Overflow a little while ago, to do with measuring how much memory your R objects are using.

<pre class="brush: r; title: ; notranslate" title="">

install.packages("pryr")

library(pryr)

object_size(1:10)
## 88 B

object_size(mean)
## 832 B

object_size(mtcars)
## 6.74 kB

This is from Hadley Wickham’s advanced R.
