Delete Block of Rows
...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.

A really simple data manipulation example
In response to those who asked for a better explanation of what the
Vilno software does, here's a simple example that gives some idea of
what it does.
LABRESULTS is a dataset with multiple rows per patient , with lab
sodium measurements. It has columns: PATIENT_ID, VISIT_NUM, and
SODIUM.
DEMO is a dataset with one row per patient, with demographic data.
It has columns: PATIENT_ID, GENDER.
