[R] Newbie question

Hi:

I'm loading in students test scores with:

> abntest <- read.table("scores.txt")

if I type:

>abntest

I get ALL the values.  I want to be able to filter it by various things such as:


if( abntesr > 90) Print abntest;

and other logical operators.  I'm sure this is simple for someone experienced.


Thanks,

Gregg Allen
