R Error in sort int x na last na last decreasing decreasing

Question

Error with sort function as below.

> l = list(1,2,3,4)
> sort(l,decreasing = T)
Error in sort.int(x, na.last = na.last, decreasing = decreasing, ...) : 
  'x' must be atomic

Answer 1

hey @ch,

The sort function is used for vectors or an atomic vector. In your case, the argument passed to the list function is not atomic list.
Sort function would not throw an error if l = list(1:4) and use sort(l[[1]])

Answer 2

Use unlist function to convert the list ta a vector and then perform sort function.

sort(unlist(l),decreasing = T)
