Here's one approach. Define f[{x_, y___}] := {x, {y}} Then map f through a list containing your lists: In: f /@ {{n, n, n, n}, {n, n, n, n, n, n}, {n, n, n, n, n}} Out: {{n, {n,n,n}}, {n, {n, n, n , n, n}}, {n, {n, n, n, n}}} ---- Selwyn Hollis Terrell Mitchell wrote: > I am trying to help a friend at a University create some plots of his > data.
