try this:
x <- c(1,1,1,1,2,2,2,2,3,3,3,3,4,4,4,4,0,0,0,0,0,0,0,0);
x1 <- array(x, dim=c(4,6))
ind <- colSums(x1) != 0
x1[, ind]
I hope it helps.
Best,

Dear friends
I have an array consist of r-rows and c-columns e.g.
x=c(1,1,1,1,2,2,2,2,3,3,3,3,4,4,4,4,0,0,0,0,0,0,0,0);
x1=array(x, dim=c(4,6))
output is
x1
[,1] [,2] [,3] [,4] [,5] [,6]
[1,] 1 2 3 4 0 0
[2,] 1 2 3 4 0 0
[3,] 1 2 3 4 0 0
[4,] 1 2 3 4 0 0
How can i ignore columns having zero sums? Help in this regard is needed. Thanks
