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. -- View this message in context: http://www.nabble.com/De...

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.
