Dear all,

I may have overlooked something but the following piece of code causes me
trouble:

> a_data.frame(1:4)
> a
  X1.4
1 1
2 2
3 3
4 4
> apply(a,2,cat)
1 2 3 4Error in ans[[1]] : subscript out of bounds
> apply(a,1,cat)
1234NULL

Is this the fact my data.frame has only one dimension ?
(and do I forget somewhere (but where ?) to specify not to 'drop'
dimension or something similar ?)

regards,
