[R] working on a vector with named elements - unname

Hi, I am working under R2.11.1 Windows.
I work with a set of parameters which is save under a vector. I think it is
easier to understand, which parameter is called in the vector by naming all
vector elements. For example, we have a vector which the parameters a,b,c,d.
Is it normal to allow, that there are two elements with the same name? I
think for lists, it is also possible. If I want to regroup the elements and
work on them, they always keep their old name. Event if I attribute to a new
name, the new name and the old name merge (lign3)

v["a"] #output 3
c("n"=v["a"]+v["c"],"n1"=v["d"]*3) # "n.a"=8 "n1.d"=18

Is there any better solution/datatype to this ?

c("n"=unname(v["a"])+unname(v["c"]),"n1"=unname(v["d"])*3) # "n"=8 "n1"=18

Thanks a lot
