testing whether two character vectors contain (the same) items in the same order

Hi All,

let?s assume I have a vector of letters drawn only once from the 
alphabet:

x = sample(letters, 15, replace = F)
x
  [1] "z" "t" "g" "l" "u" "d" "w" "x" "a" "q" "k" "j" "f" "n" ?v"

y = x[c(1:7,9:8, 10:12, 14, 15, 13)]

I would now like to test how good a match y is for x.  Obviously I 
can transform the letters in numbers and use a rank test, but I was 
left wondering whether this is the only solution and whether there 
are more appropriate solutions that are already implemented in R (I 
am not going to reinvent the wheel if I can avoid it).
