You can use the [[ operator defined f

Thanks for the suggestion Christian. I'm trying to avoid expanding the dist
object to a matrix, since i'm usually working with microarray data which
produces a distance matrix of size 5000 x 5000.
If i can keep it in its condensed form i think it will speed things up.
Is my thinking correct?

Try
dMat <- as.matrix(dist(x))

Hello:
Does anyone know if there exists a package that handles methods for [ for
dist objects?
I would like to access a dist object using matrix notation
e.g.
dMat = dist(x)
dMat[i,j]
Thanks in advance to anyone who can point me in the right direction.
