I like Duncan's idea. I doubt I have ever used head on a function
for real, but tail of a function can be handy for seeing the structure
of the return value. I agree that this is only likely to be used interactively.
Okay, I'll put in those changes (with Brian's improvement). One other one I'll look at:
If a matrix doesn't have row names, I might add names like '[nn,]' to it, so I get results like
x <- matrix(1:100,ncol=2)
tail(x)
[,1] [,2] [45,] 45 95 [46,] 46 96 [47,] 47 97 [48,] 48 98 [49,] 49 99 [50,] 50 100
instead of the current
tail(x)
[,1] [,2] [1,] 45 95 [2,] 46 96 [3,] 47 97 [4,] 48 98 [5,] 49 99 [6,] 50 100
I just want to be careful that this doesn't mess up something else.

I think this could be being too "helpful". Using tail on a matrix may often be done in a program so I think leaving things as they come is the best policy.
