I think the same problem exists - you get a billion line output (with 50
vars and subset size of 10). I think SAS had something like this, but
displayed only the 'best' one.
This suggests to me a) know a lot about your data before doing this; b)
look for small subsets; or c) use some sort of stepwise (and penalized)
procedure (AIC or BIC or Mallows' Cp).
We're talking the art of statistical analysis now.
