...) object.size(get(w)))
as.matrix(rev(sort(z))[1:5])
}
mysize()
When I test the lines inside the function it works fine:
> z <- sapply(ls(), function(w) object.size(get(w)))
> as.matrix(rev(sort(z))[1:5])

But when I try to run the function, it produces an error:
> "mysize" <- function() {
+ z <- sapply(ls(), function(w) object.size(get(w)))
+ as.matrix(rev(sort(z))[1:5])
+ }
> mysize()
Error in rev(sort(z)) :
error in evaluating...
