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.

+ 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?
