Delete Block of Rows

I am trying to delete a section of rows from a data frame (based on no condition).  Lets say my data frame has 200 rows and I want to delete rows 1 through 25.  How would I do this?

I know x[ -1, ] deletes the first row (or any desired row).  I tried using different variations of this, like x[ -c(1:25), ] but that didn't work.  I also tried writting a few functions, for example:

deleteRows <- function( data, s, e, ) {
for( i in s:e )
data[ -i, ]
}
deleteRows( ds, 1, 25 )

But that didn't work either, it only deleted row 25 (i'm new to writing functions).
Any thoughts on how to solve my problem would be appreciated.
