finding substrings

[Dave Evens <devens8765@yahoo.com>]

Dear all,

I would like to find the exact match of a
substring(/sub-vector) within a string (/vector). For
example, suppose I have

x <- c(F, F, F, T, T, F, F, T, T, F, F, T, T, T, F, F,
F, F, F, T, T, T, F, F, T, T, F, F, T, T, T)

y <- c(F, F, T, T, F)

What I would like to do is find the exact match of y
in x with possible overlapping, i.e. 

return back

2 6 23

I couldn't get it to work with matchList.

Thanks for any help in advance.

Dave
