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
