Can you give a simple example of what you are trying to do?
Would the following help?
> x <- sample(10)
> diffMat <- outer(x, x, "-")
> x
[1] 1 10 5 8 9 6 3 2 4 7
> diffMat
[,1] [,2] [,3] [,4] [,5] [,6] [,7] [,8] [,9] [,10]
[1,]0 -9 -4 -7 -8 -5 -2 -1 -3-6
Do you mean something like
abs( my_vector[i] - my_vector[j] )
See if reading help("subset") helps.

Hi,
I'm trying to figure out how to properly construct a graph of
frequencies of a difference between 2 values, that is | i | - | j |.
I'd like to know the best way to store the actual data because of course
doing my_vector[i -j] will not work because the index could be negative.
I know there's
