Dear all,
I would like to thank you for you answers
This worked for me

What I want to do now is to keep all the vector elements (only numbers) without the zeros!. How I can do that?

Someone already suggested that you use match(),
which does what I think you want.  Read its help file
for details.
 
> A <- seq(1,113,4)
> match(c(9, 17, 18), A)
[1]  3  5 NA

Thanks a lot! This works.
Now I want to do the opposite
let's say that I have one sequence 
for example 
check in image 
http://imageshack.us/photo/my-images/4/unleduso.png/
column A (this is a seq(1,113,4)
and I want when I get the number 9 to say that this is the third number in the seq (1,113,4). everything about the seq(1,113,4) is known and I want when I get one of the number of the sequence to say which is its order.
How I can do that?

  is.element(myvector, seq(1,800,4))
or, if you like typing percent signs,
  myvector %in% seq(1,800,4)
