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.
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.
