Newbie question

abntest[abntest$abntesr > 90,]

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

Hi, get yourself one of the many free manuals that you can download online.
They answer the easier questions. Tom Short's R reference card may also be
very helpful to have on the side when you are an R novice.

Cheers,
