R help - Jan 2008 - how to generate sequence "a" - "z"

I suppose it's very simple but I can't find the way to generate a
sequence of
characters, e.g. from "a" to "z".
Could you please help me with this?

Hello,

Sequences of letters can be generated by typing

LETTERS #for capital letters or
letters #for small letters

Best wishes

If you want the standard collation sequence, use the letters variable, 
as others have said.

If you want the sequence that applies in your locale (where does "?" 
fall?), it's harder.  I don't know a simple way, but this gives you 
collation order in the German locale in Windows:
