Implementation of skyline query or efficient frontier

Question

I know there must be an easy answer to this but somehow I can\'t seem to find it...

I have a data frame with 2 numeric columns. I would like to remove from it, the r

Answer 1

In one line:

d <- matrix(c(2, 3, 4, 7, 5, 6), nrow=3, byrow=TRUE)
d[!apply(d,1,max)

Edit: In light of your precision in jbaums' response, here's how to check for both columns separately.

d <- matrix(c(2, 3, 3, 7, 5, 6, 4, 8), nrow=4, byrow=TRUE)
d[apply(d,1,min)>min(apply(d,1,max)) ,]

     [,1] [,2]
[1,]    5    6
[2,]    4    8
