When I encounter memory errors, I like to see the size of the objects in

memory, so I modified one of the examples:

z <- sapply(ls(), function(x) object.size(get(x)))

as.matrix(rev(sort(z))[1:10])

This works fine if I run it as is, but if I try to place it inside a

function, I get an error (see below). I tried using sort.list and

unlist, but I couldn't get it to work. I don't understand why the

commands work by themselves but not in a function. Its probably a

simple fix, can anyone enlighten me?

Thanks, Roger.

> "mysize" <- function() {

+ z <- sapply(ls(), function(x) object.size(get(x)))

+ as.matrix(rev(sort(z))[1:10])

+ }

> mysize()

Error in sort.list(z) : 'x' must be atomic for 'sort.list'

Have you called 'sort' on a list?
