I have data that I want to export to a text file.
s = Subsets[{a, b, c}];
r = Table[s[i]] + 1, {i, Length[s]}];
Export["file.TXT", {r, s}, "Table"]
{} {1 + a} {1 + b} {1 + c} {1 + a, 1 + b} {1 + a, 1 + c} {1 + b, 1 + c} {1 + a, 1 + b, 1 + c} {} {a} {b} {c} {a, b} {a, c} {b, c} {a, b, c}
But I need to Export data vertically.

Export["file.TXT", Transpose[{r, s}], "Table"]? $\endgroup$Map[# + 1 &, s, {2}]$\endgroup$
