I use the dim(names)[1] and dim(x)[2] along with length(x) with varying 
levels of frustration depending on the object which I am trying to get 
the dimensions.  I found the reference to seq_len interesting since it 
is a function that I have never seen (probably just missed it reading 
the docs).

I was hoping someone could expand on the benefits of seq_len.

Happy Holidays
